* providers/imap/camel-imap-store.c (unsubscribe_folder): Don't
free the hash table key if the folder wasn't found in the hash
table. I'm not sure where the bug is/was that made it possible to
add a folder to the tree after creating it failed, but now if that
happens, it won't crash if you try to delete it again. (#11492)
