  lib-storage: Fix accessing the same "raw" mailbox multiple times in process.

If the same file was opened as the raw mailbox multiple times, the previous
mail_index was cached by mail-index-alloc-cache. Opening it the second time
already contained a mail in the index, so trying to add another one logged
an error:

Error: Log synchronization error at seq=1,offset=256 for (in-memory index): Append with UID 1, but next_uid = 2
