fix(appdrawer): Correct pin/unpin icon logic in context menu

The drawable for the "Pin to top" context menu item was inverted. It showed the 'unpin' icon (`pin_off`) when an app was already pinned and the 'pin' icon when it was not.

This has been corrected to show `pin` when the app is not pinned and `pin_off` when it is.
