[clang-tidy] Remove IncludeInserter from MoveConstructorInit check.

This check registers an IncludeInserter, however the check itself doesn't actually emit any fixes or includes, so the inserter is redundant.

From what I can tell the fixes were removed in D26453(rL290051) but the inserter was left in, probably an oversight.
