Steps to reproduce the problem:
1. Enable keyboard shortcuts
2. Use g + i  to goto Trash(ensure that trash has a deleted mail)
3. Use *+a to select all conversations in trash and hit # to delete

What is the expected behavior?
The conversations should be deleted forever.

What went wrong?
Converstaions remain in Trash and the message "The conversation has been moved to the Trash.  Learn more..." is notified.

Did this work before? No

It might be an intended behavior. But I feel it'd be good if we allow this. Kindly let me know the apprehensions if any. Thanks!
