Thiago Macieira ea6675374f QString: fix comparisons to null strings in ucstricmp
Commit 8f52ad9fe0 ("ucstricmp: compare
null and empty strings equal") made sure empties and nulls would compare
equally, but may have broken the null vs non-empty comparison (which was
not tested). The commit message also said that it expected all callers
to handle null before calling into those functions, but that's not the
case for QStringView created from a null QString: the incoming "a"
pointer was null.

So just remove the checks for null pointers and rely on the size checks
doing the right thing.

[ChangeLog][QtCore][QString] Fixed a regression from 5.9 that caused
comparing default-constructed QStrings to be sorted after non-empty
strings.

Task-number: QTBUG-65939
Change-Id: I56b444f9d6274221a3b7fffd150c83ad46c599b6
