tst_qvariant: fix comparison ambiguity for QMetaEnum value

Under certain circumstances, VS2015 reported ambiguous options in using
the operator>(Enum,int) operator.  This change adds a static_cast<qint64>
to remove any ambiguity.  In the process of testing this change, a gap
in the existing logic was identified: the handling (just in the test
code) of large negative enum values.  Consequently, and additional
test case was added, and additional if-conditions were added to account
for that case.
