Take care of NULL data from QStringView in QCollator
Back-ends need to catch NULL data so as not to call system APIs with
invalid pointers.
[ChangeLog][QtCore][QCollator] Fixed a regression introduced in 5.14.0
that caused QCollator not to operate with default-constructed QStrings
and print a warning on Windows.
Fixes: QTBUG-81673
Change-Id: I2eafe1e188b436afcca3cf2ecdf98bba707c44c9
