Bug 1511311 - [marionette] GeckoInstance classes should not overwrite already set custom preferences. r=automatedtester Custom preferences as passed into both classes via the constructor are getting set in the base GeckoInstance class. But both the DesktopInstance and FennecInstance classes could override those custom preferences if they have the same preference set as required preference. As such the custom preference doesn't have any effect. This patch allows both classes to override required prefs with a different value.
