Summary:
When running tck tests there was a peculiar behavior where sometimes some queries worked, and sometimes they failed. Nothing was failing when memgraph was restarted between each query (scenario) - which points to MATCH DETACH DELETE not working correctly.
What was happening is the following: some transaction would update the record in version list and set it's expiry to it's id. Along with that some transaction would query the mentioned record - and would set the hints flags for that expiration transaction status (which was aborted - which is fine at this moment). After some while, because the record is not really deleted because it's not aborted some other transaction would modify it's expiry transaction (this time making the transaction commited), but because the hints flags were not updated - they would still return the status for the old transaction - which was aborted. This made some records available even though they were deleted.

- provided a test infrastructure (fixture and macros) to facilitate testing and increase readability
- split tests into multi-transaction update, VersionList::find and general Mvcc testing
- multi-transaction update tests have been refactored (i *think* nothing got deleted, but it was a mess so I don't guarantee)
- changed all multithreaded tests to be single-threaded because multiple threads were not necessary
- changed transaction naming from T5, T8, T10 to T1, T2... for consistency with actual transaction indices
What still needs to be done:
- Gleich and Gradicek need to review the infrastructure (possible improvements)
- multi-transaction update tests need to be addressed by Gradicek (see "TODO gradicek" in code, discuss with Flor)
- the wiki/draw.io documentation needs to be updated. it is not imperative that all the tests be drawn in draw.io, only the general infrastructure explained. perhaps only a few examples drawn. Gradicek discuss with Flor

This should fix the integration query engine test. I'm not exactly sure what caused the SEGFAULT to occur, but from my debugging sessions; I would say, as an educated guess that it's closely related to logger. What I believe happens is that logger gets somehow initialized from the dynamic_library when it's opened. And when the library is closed the corresponding logger is freed, but, other parts of memgraph still see that instance of logger and trying to use to emit code makes the whole thing crash. I've removed one include of logger from something which gets included in the hardcoded queries, but I noticed there are some more.
I've changed the dlopen to now open with DEEPBIND, which should cause symbols to be resolved locally and not globally and stop the logger from the dynamic lib to interfer with the one used in the rest of memgraph.
