When notifications become non-RON, we dont reset the largeicon margins. This CL fixes issue by restoring the margin for expanded templates

Flag: android.app.ui_rich_ongoing
Test: Post a ron with large icon and update it to make it non ron. See large icon moved left to expander with correct paddings and margins
