Do not move the cursor if the cursor is invisible
when display configuration is changed. This was to
make sure that X11's cursor stays inside a display, as
reconfiguring display can potentially move the cursor
to outside of displays.

I think this is no longer a concern, and I'll
replace this with just a notification after merged to 65.

This also fixes the test harness that assumes the cursor
is visible by default but wasn't.

BUG=773479
TEST=covered by unit test. also tested on device.
