[PR] Fix issue #1399 EXISTS doesn't handle non-existent labels (#1400) [age]

   Fixed issue #1399 where EXISTS doesn't handle non-existent labels. However, the issue actually is due to the extra processing (read: extra distance between the AST nodes) that prevented the transform logic from being able to resolve variables created in previous clauses further than one parent up.
   
   Added logic to allow the `find_variable` function to search up the parent parse nodes.
   
   Added regression tests to cover these cases.
