  Fix a potential crash situation when using IMAP voicemail
  
  If calling into VoiceMailMain when using IMAP storage, it was
  possible to crash Asterisk by hanging up the phone when prompted
  for a voicemail mailbox. This patch fixes the issue.
  
  While it may appear that this patch is superficial, it allows code
  execution to continue to the failure case just below the IMAP_STORAGE
  code block where this patch has been applied
  
  (closes issue #14473)
