Carlos Garnacho 26c2633b2c clutter: Update device on touchpad gesture events
With commit be3bca01a7 in place, we now possibly skip early calls
to clutter_stage_repick_device() happening early during initialization.
These were also indirectly the ones that eventually ended up in
the first call to clutter_stage_pick_and_update_device() actually
initializing the PointerDeviceEntry.

With this no longer happening, we may end up with no PointerDeviceEntry
implicitly set up after initialization, which may fail if the first
event received from the seat pointer does not in fact trigger the
clutter_stage_pick_and_update_device() call necessary to make things
work from there on.

And this does indeed happen on touchpads, since the first input event
obtained after CLUTTER_DEVICE_ADDED is CLUTTER_TOUCHPAD_* instead
of CLUTTER_MOTION. This finds an unset PointerDeviceEntry and crashes
since the pointer device does still have no "presence" on the stage.

Fix this by making CLUTTER_TOUCHPAD_* events also trigger a
device update, so the fist event handled does always trigger the
necessary device update.
