Chris Young 0b67394618 Don't attempt to close a public screen we're not the owner of.
I've never been entirely clear on what the correct approach here is, but OS4 has a feature where it will auto open/close a public screen for you.  In this case, in the microseconds between unlocking that screen and attempting to close it, OS4 has already disposed of the screen and NetSurf has crashed, so we assume the owner will handle the closing instead.
