Suppress "unable to send message to tab" for protected pages

[rhelmer]

I've filed this issue upstream, but since RS01 shipped with a fork of this module I wanted to track it here too:
mozilla-rally/web-science#79

Since this was noticed by an internal user (@cpeterso, reported in Slack) we should assume that other users might be annoyed by this. I'd like to pick it up in an update.

@hamilton we should suppress this entirely from non-debug builds ^

Sorry this is a core add-on bug, filed mozilla-rally/rally-core-addon#582 for that.
