Fix crash when removing phantom tags

Browse Source 
Normally a tag is stored in both session and torrent's fastresume.
A phantom tag is a tag that is stored in fastresume but not in
session.
This crash can occur when user resets his config file and choose
to remove tag from torrent.

Closes #10569.
