When slow mode is enabled it's possible to open the slow mode dialog again to disable it or to update slow mode settings. The problem is that in this case, the button for saving still has the label "Enable" which is confusing.
This changes the text on the button from "Enable" to "Update" when slow mode is already enabled.
If reload a page after enabling slow mode and open the slow mode dialog again it would show a slow mode interval but wouldn't show Enabled Until value. This PR fixes it.
