[Dextrose] [PATCH][Sugar] Fix globalkey touchpad corner case

[Martin Abente]

This patch is not intended for upstream. Is just a minimal
hack to fix a corner case, where the palette must be created
before the tray icon or global can toggle the touchpad mode.

A serious fix could consist on moving the mode-switching
code from extensions/deviceicon/touchpad.py to a touchpad
module at src/jarabe/model.

This model should provide a public mode_toggle method and 
also emit proper signals when it occurs. This way different
pieces of sugar code will be able to interact with the touchpad
properly without repeating code all over.
