Alice should verify her own encrypted messages

**Detailed Description**
If Alice sends an encrypted message, she should be able to optionally specify if she wants to decrypt her own messages received from mirror so that any malicious activity is detected.

**Actual Behavior**
Alice checks signatures and hashes, but not the actual contents on the business message. This could lead to a case where her own state is out of sync with the intended recipients of her message:
-She assumes the message is correct and updates state
-Others will fail to decrypt and won't update state

**Expected Behavior**
Given an optional parameter, alice either assumes hash/signature is sufficient for verification or goes to the extra step of decrypting her own message.
