the data is received.

Summary:
This diff fixes the variable expand operator to work correctly then the start
and destination nodes use the same symbol or when the destination symbol is an
existing symbol.
Previously, the variable expand operator produced paths that were both
completely wrong (they shouldn't have been produced) and nonexistent (they
didn't even exist in the storage). Invalid data was produced because of a
wrong equality check that was introduced in D1703.
This issue was reported externally and the supplied test case was:
```
CREATE (p1:Person {id: 1})-[:KNOWS]->(:Person {id: 2})-[:KNOWS]->(:Person {id: 3})-[:KNOWS]->(:Person {id: 4})-[:KNOWS]->(p1);
MATCH path = (pers:Person {id: 3})-[:KNOWS*2]->(pers) RETURN path;
```
Also, tests have been added so the behavior remains correct.

Summary:
`DUMP DATABASE` used a separate transaction to read database data. That
wouldn't be an issue if the query was correctly disallowed in multicommand
transactions. Because it was allowed the output wasn't transactionally correct.
Instead of disabling `DUMP DATABASE` in multicommand transactions this change
fixes it so that it works properly in multicommand transactions.

Summary:
Before this change properties were joined by ", " and returned as a single string,
which was ambiguous for properties that contain ", ". This diff solves this
problem by returning properties as a list type.

Summary:
This diff fixes the issue for label name (and edge type/property)
with spaces and special characters to avoid possible OpenCypher injections.
Consider an example where label name is 'hello :world'. `DUMP DATABASE`
used to return query which creates a node (u:hello :world) - i.e. node
that contains two labels 'hello' and 'world'. This fix escapes names to
create the following node with exactly one label as expected:
```
(u:`hello :world`)
```
