don't swallow HTTP errors from create_event

tests weren't patching out create_event (which is invoked every time a
user logs in). This was getting caught by our egress proxy on jenkins.
We didn't notice because the event handler code was swallowing all
exceptions and not re-raising.

This changes that code to no longer swallow exceptions. Since we did
that, we also need to update all the tests that test log-in to mock
the call
