Session restore fails after INT, TERM or HUP signals if set to "after-a-crash"
Follow-up to #161 (comment 43763).
It actually never worked because it was broken by a7718579 (which is incomplete rather than incorrect) before it was released in Mousepad 0.5.6. The autosave-*
files from the previous session are then considered orphaned and must be deleted manually.
It works fine in a "real crash" though (e.g. after a KILL signal), or for other session restore modes.
