Bug 1404049 - fix that mail.imap.use_literal_plus set to false may have no effect.

This is because it was only used in response to a CAPABILITY imap request. However, often CAPABILITY response occurs without a request so TB sees no need to do a request. Fix by moving the usage of use_literal_plus to where LITERAL+ capability is actually used.
