bad SQL query in project_issue_query_result()

if you end up in project_issue_query_result() with the $query object being NULL, you hit some completely bogus code. normally, this never happens, since project_issue_query_parse() always adds something to the query if it would otherwise be empty (the default issue states).

however, the fix for http://drupal.org/node/57023 changed project_issue_query_parse() in a way that left $query NULL. this exposed the bug with the dead SQL query i'm talking about here. regardless of what happens in #57023, project_issue_query_result() should be organized such that we *know* $query always has something, and we should rip out dead code that's never being hit.

stay tuned, patch forthcoming.
