imap: Code tidy up prior to adding support for the CAPABILITY command

Browse Source 
* Changing the order of the state machine to represent the order in
  which commands are sent to the server.

* Reworking the imap_endofresp() function as the FETCH response doesn't
  include the command id and shouldn't be part of the length comparison
  that takes into account the id string.
