Fix parse tree of DROP TRANSFORM and COMMENT ON TRANSFORM

Browse Source 
The plain C string language name needs to be wrapped in makeString() so
that the parse tree is copyable.  This is detectable by
-DCOPY_PARSE_PLAN_TREES.  Add a test case for the COMMENT case.

Also make the quoting in the error messages more consistent.
