Keyguard: fix not shown overlay widgets from system

google derp....due that if widgets are disabled current AOSP
code just add the default widget. Then checkAppWidgetConsistency()
detects a widget which was added and the complete method is non op.
Whatever lets handle the whole process over checkAppWidgetConsistency()
on widget disabled it tries to bind the default widget over overlay if
this is without sucess it falls back to the system one.
Safemode falls always to the system one

This fixes as well an issue that the saved default id in LockPatternUtils
is not reseted back to default if all widgets were deleted from the user.
Based on an old patch from Danesh. Thanks for the suggestion

Keyguard: let the user drag the challenge down if widgets are disabled

for the system clock widget this does not make much sense
but since our system default is cLock it makes sense to
allow it to see more content.
