Please describe the problem:
When you edit the type of encryption used by an imap server in the accounts list, the change has no effect unless you restart evolution.  Nothing in the UI suggests this will be the case however, which causes much confusion to an unitiated user.

Steps to reproduce:
1. Add a new account, naming an IMAP server for which TLS does not work, but choosing TLS as the encryption.
2. Note that the connection does not work.
3. Change the encryption from TLS to either SSL or "No ecryption" (whichever will work for your server)
4. Note that the connection still does not work.
5. Restart evolution
6. The connection should now work


Actual results:
Connection does not work at step 4, but does at step 6.  No user interface appears that explains that this will happen.

Expected results:
Either the connection should work at step 4, or a dialog should appear to indicate that evolution must be restarted for the change to take effect.

Does this happen every time?
Yes

Other information:
I'm using the Windows port of Evolution.  Not sure if this is relevant.
