Bug 1358402 - Keep 'marionette.defaultPrefs.enabled' around as fallback. r=ato a=tomcat With bug 1344748 landed the default preferences and their handling has been changed. Builds starting with Firefox 54.0 can handle that, but previous releases don't enable Marionette at all after a restart under special conditions (invalidating 'update.status' file before the restart). To prevent the bustage we have to keep the preference 'marionette.defaultPrefs.enabled' around until the next ESR release is out. MozReview-Commit-ID: AB3liJlb6M7
