Fix uninitialized prompt buffer in imap_mailbox_rename(). (closes #3819)

This is a patch from OpenBSD to initialize the newname buffer in
imap_mailbox_rename().  Previously it would generate random garbage in
the prompt.

This version of the patch initializes the prompt to the old mailbox name.

Thanks to TAKAHASHI Tamotsu for finding this patch.
