fix(custom-views): Fix unsaved changes not triggering correctly (#76869)

This PR fixes an issue with unsaved changes where manually changing a
view's search query from unsaved changes back to the original query
would result in the unsaved changes indicator still appearing. If the
query matches the views existing query, it should always show up as not
having unsaved changes.
