Cannot send message with just enabled account

Everything in UI seemed as working fine, but the message is just lost,
even there was printed a runtime warning on the console.
This is fixing couple things along this issue:
- differentiate between NULL and invalid pointers/objects
  in new e_mail_folder_uri_...() functions
- report error to UI if mail_session_send_to_thread() fails to find
  corresponding transport service
- call e_mail_store_add_by_account() in mail_store_load_accounts()
  (a side-effect of this change is no code duplication and unified
  processing of the same action)
