[PATCH 3/2] Disable certificate verification if there is no certificate

[Sebastian Spaeth]

imaplib2 always attempts to verify a certificate if a verification
callback function is passed in, even the certificate is None
specified. Disable the verification excplictly by setting the
verification function to None in that case.
