Agi Sferro 969a457a69 Bug 1605256 - Add exception type to message. r=snorp
This commit does two things:

- It exposes the error that caused the test to fail in our logs, so it would
  appear like so:

```
TEST-UNEXPECTED-FAIL | org.mozilla.geckoview.test.ExtensionActionTest.setIconSvg[#pageAction] | java.lang.AssertionError: We shouldn't get here
```

- It catches exceptions that are raised before any test code is run and outputs
  a different message (since those failures do not depend on the test at all),
  like so:

```
ERROR runjunit.py | The previous test failed because of an error in the test harness | org.mozilla.geckoview.test.rule.TestHarnessException: java.lang.RuntimeException: We shouldn't get here
```

This will hopefully help with spurious intermittents and understand when a
failure changes.
