Bug 1884216 - Fix test_dom_quota_try.js to deal with different number of errors in nightly builds; r=dom-storage-reviewers,asuth

The error propagation during temporary storage initialization is a bit
different in nightly builds due to the use of OK_IN_NIGHTLY_PROPAGATE_IN_OTHERS
macro. This patch also fixes the case when logging to telemetry is disabled
completely.
