Admin password protected settings not shown correctly

[Huster-at-github]

Just a small bug, but some administrators could be confused:

Actual behaviour

• Changing a admin password protected setting
• Press "Cancel" at password prompt
• Nevertheless setting seems to be set
• Pressing browsers F5: No changes
• Pressing browsers Strg-F5: Loads real settings again

Expected behaviour

• Show real setting after "Cancel" was pressed

---

• Press "Allow sharing with groups"

• Press "Cancel"

• Wrong setting is displayed
• F5 does not help
• Strg-F5 displays the correct setting again

---

Needs help from JS experts. The dialog currently does not have something for when cancel/esc is pressed.
