When deleting a Rally tag, the warning message shows items still tagged

Issue/Introduction

When deleting a tag, a message is shown indicating items are still tagged even though no work items are showing up with that tag.

Cause

The tag delete routine also searches on work items that are in the recycle bin and in closed projects, however the user interface and our API do not directly look at those.  Therefore, there can be a discrepancy between what the user interface and API show and what the delete warning shows.

Resolution

There isn't a method to find deleted work items and items in closed projects that have a specific tag.  If due diligence has been performed in tracking down items in a workspace and the tag delete warning message still shows items with that tag, then those items are deleted or in closed projects and the tag can be safely deleted.

Additional Information

Warning is:

ARE YOU SURE YOU WANT TO DELETE THIS TAG?
