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:
Use Unwind + ScanAllByLabelPropertyValue logical operator to

Summary:
- Add the `mgp_must_abort(const mgp_graph *graph)` C API.
- Add the `ProcCtx.must_abort()` Python API.
The usage is very simple -- the function returns a boolean indicating whether
the procedure should abort.
