[PATCH] D76549: [clang-tidy] Fix RenamerClangTidy handling qualified TypeLocs

Previously if a type was accessed with a qualifier, RenamerClangTidy wouldn't rename the TypeLoc, this patch addresses this shortfall by trying to find the Unqualified TypeLoc first. Also fixed a broken test case that was dependent on this broken behaviour.
