Summary:
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.

Summary: Db_accessor is tied to one transaction, and as such each query should work on seperate db_accessor.
