Subject: [PATCH] Fix reading empty tags from plugin descriptions

If a plugin's description field contained `{{BASH:}}`, LOOT would
extract a Bash Tag with a zero-length name string. This would then cause
the user to be unable to save the metadata editor for that plugin,
because it would recognise that Bash Tag as being invalid.
