Purging deleted Tasks does not purge deleted Task metadata (even for non-deleted tasks)

[toddgee]

Opting to purge deleted tasks does not purge deleted metadata (tags) on non-deleted tasks.

If this is As Designed, then a new menu item is required to purge deleted meta-information. I'd suggest, however, that purging deleted data should purge ALL deleted data -- including Task metadata.

Steps to reproduce:

• Add a Task
• Add the Task to a new Task List
• Remove the Task List from the Task
• Select the "Purge Deleted Tasks"
• Export Tasks
• View exported Task .xml file

Expected:

• Test Task should not contain a tag with a non-zero 'deleted' field.

Observed:

• A tag exists for the deleted Task List (tag)
