Fix complex MERGE causes crash (#897) (#961)

Fixed the complex MERGE crash, which was due to storing variables
in tuple positions that did not exist. This happened on MERGE
commands where there wasn't a RETURN clause.

Added logic to catch these and handle appropriately. Meaning,
discarding the variable results, instead of storing them.

Fixing this issue has highlighted the need to fix variable reuse
in the MERGE transform itself. This is because MERGE preprocesses
the path before handing it off to anything else.

Added regression tests.
