Extend QTest::failOnWarning() to a no-parameter fail-on-any-warning

Many users (albeit mostly in qtdeclarative) of failOnWarning() are
passing a catch-all regexp, which is only supported when regular
expression support is enabled. Make their lives easier and those
checks independent of the feature by adding a third overload, taking
no parameter, that fails on any (unanticipated) warning.

Implementation is trivial - just put a null QVariant in
failOnWarningList; it won't match either check on the entry that might
exempt a test from failing on a warning, so any warning at all will
trigger failure.

[ChangeLog][QtTest] QTest::failOnWarning() now has a no-parameter
overload to support the common case of fail-on-any-warning, without
needing to construct a match-everything regular expression.
