Workaround for misbehaving [UIScreen screens] in iOS 7.1

Browse Source 
On iOS 7.1 [UIScreen screens] sometimes returns empty NSArray which
is against documentation and causes immediate application crash.
This workaround uses [UIScreen mainScreen] in case [UIScreen screens]
returns empty NSArray.

Task-number: QTBUG-37601
