[Bug] own mmses are not restored into original conversation

[i-am-rumburak]

Describe the bug in sms "conversation" there may be smses and mmses from both parties: me and other party. when smses/mmses are backed up and then restored then smses/mmses sent by other party are correctly restored under other party phone number. my mmses are restored to new sms/mms conversation under my own phone number. they are not a part of original conversation.

To Reproduce Steps to reproduce the behavior:

1. find a sms/mms conversation where both parties send sms/mms, you and somebody else
2. backup sms/mms
3. delete original conversation
4. restore sms/mms
5. notice that new conversation is created with your number and it contains all mmses from original conversation that were sent by you there.

Expected behavior when backing up sms/mms conversation i expect restoration to restore original form, not creatimg additional comversation
