**Background:** Temporary watchlist options interface appears broken in VisualEditor, due to our Watchlist Expiry changes.
**Acceptance Criteria:**
* Restore previous VisualEditor behavior, in which only the original watchlist checkbox is displayed
**Visual Examples:**
//The interface when saving changes in VisualEditor looks like this://
{F31962108}
There is an unexpected checkbox next to "Watchlist time period:", and the dropdown that should be there instead is missing. (Checking or unchecking that checkbox does nothing.) The "Watch this page" checkbox works as normal.
//Source editor interface, for comparison://
{F31962111}
Expected behavior: either the same interface appears as in source mode (related task: T251348), or at least there aren't any non-functional checkboxes.
