Fix IMAP transport instantiation

This reverts the approach to IMAP transport instantiation back to how it
was done prior to 2a<I>b6 which introduced the usesslcontext parameter.
This reduces code duplication and importantly make instantiation work
again because self.IMAP4 and self.IMAP4_SSL do not exist.
