Change behavior of Room Bulk Edit to not overwrite slider button settings.#1761

Usecase: I needed to add restrictions for a student so that they can only use a specific admin bathroom throughout the day. I selected all of the rooms in Classrooms folder and bulk edited the visibility setting to remove this student’s access. Because bulk edit overwrites when you make changes, it also blanked out all of my Restrictions for Now and Restrictions for Future rules. This is a frustrating use pattern because even though I did not change that setting, because the default setting is off it applied that setting to all of the rooms I was editing.

Suggested Pattern: When bulk editing rooms, only settings that have been physically edited should be changed. Even if the sliders default state is off, it should not transfer that over unless I explicitly edit the setting to turn it off.
