Bug description

When disappearing messages are enabled on a chat, call records such as "You received a call from..." or "You called..." are not deleted, but should be deleted.

Steps to reproduce

• Enable disappearing messages in a chat
• Call or receive a call. Also send a text message.

Actual result: When the text messages disappear, the call records remain
Expected result: When the text messages disappear, call records should also be deleted

Device info

iOS version: 10.3.1
Signal version: 2.11.1

I looked into this and it seems that the fundamental issue is that OWSCall is a TSInteraction while OWSMessage is a TSMessage which has _a lot_ more fields and metadata associated with it. I'm happy to work on this but would like some guidance from @michaelkirk or @charlesmchen on the right approach because I can think of several ways to begin.

This is working as intended.
