1435805 - Add telemetry to measure Sent Tab failures

Description

[James Hugman [:jhugman] [@jhugman]]

In anticipation for re-working send-tab via pushbox, we should have a good idea that what we're doing is working.

This bug needs to log notifications that fail to be decrypted and decoded.

This is especially tricky given that one of the main causes of decryption failure is the extension failing to run. 

Log a failure: 

1. in the extension when a message is received, but zero tabs have been found.
2. in the app when a message is tapped on, but the message needs decrypting (as if the extension failed).

(1) is needed in the extension because we proactively try and reduce the number of Tap to begin messages in a number of ways. We want to count these, even if the user doesn't get to see them.
(2) will undercount the messages, given that the user can dismiss the notification before the message is decrypted (thus losing the message entirely).
