msgstore: delete pending headers when done or cancelled

The msgstore keeps a map of UIDs it has requested headers for. The map
is only cleared of pending headers when either an error or a valid
header is received. This can lead to pending headers not being removed
from the list (and therefore never re-requested) if a user has navigated
away from the directory before the response is received.

Delete the pending headers list if the request is finished or cancelled.
