Invalid macro resolution for table identifiers

[izeigerman]

Expression which include a table identifier resolved through a macro like:

FULL OUTER JOIN @SQL('@target') AS tgt

resolves into the following AST:

  (JOIN this:
    (TABLE this:
      (COLUMN this:
        (IDENTIFIER this: orders, quoted: False), table:
        (IDENTIFIER this: sushi, quoted: False)), alias:
      (TABLEALIAS this:
        (IDENTIFIER this: tgt, quoted: False))), side: FULL, kind: OUTER, on:
...

The TABLE node contains another COLUMN node instead of just IDENTIFIERS. For comparison here's the same AST, but with the value inserted directly instead of through a macro:

  (JOIN this:
    (TABLE this:
      (IDENTIFIER this: orders, quoted: False), db:
      (IDENTIFIER this: sushi, quoted: False), alias:
      (TABLEALIAS this:
        (IDENTIFIER this: tgt, quoted: False))), side: FULL, kind: OUTER, on:
...

Because of the invalid AST other sql-related functionality like eg. exp.replace_tables doesn't work correctly.
