Title: Also check cc for duplicates in group MMS

Commit 0b4fe84 was intended to fix #1018, however it doesn't check the presence of the local phone number in the Cc header. This amends that, and I can confirm that it at least fixes the issue on my device. This can be marked as a feebie if you want; it was a real quick fix.
