bug 1492499: marionette: warn on TimedPromise bailing; r=automatedtester We often use TimedPromise to ensure Marionette does not unexpectedly block on a promise that, for whatever reason, does not resolve. It can however be useful to be alerted when they don't, as it quite often means there is an underlying problem. Depends on D8406 Differential Revision: https://phabricator.services.mozilla.com/D8407
