SF-3815 Inform Bugsnag which exceptions are handled

[pmachapman]

I found it impossible to test this locally - even when I set the NotifyReleaseStages to include "development", no exception was reported to bugsnag.

I think the best place to test this PR is on QA.

I remember the same thing when I wanted to see error reports on bugsnag from dev, but I couldn't shake it to do that. I wonder if bugsnag is filtering out dev reports and we just aren't seeing them there.
Let's get this to QA and we can test how errors are reported there.
