Found a grievous logical error in get_vm_state_by_imapuser.

The imapuser being passed in was never getting compared to imapusers of any of the vm_states
in the vmstates list.

I also found some places in the code where I used my typical brace style and changed it to match
the typical Asterisk brace style.
