Fix compilation of moc generated file with MEMBER properties

If the object has only MEMBER properties, without any other property
specifying READ, the generated will fail to compile with this error:

tst_moc.moc: In member function ‘virtual int ClassWithOneMember::qt_metacall(QMetaObject::Call, int, void**)’:
tst_moc.moc:3810:42: error: ‘_v’ was not declared in this scope

That's because the '_v' is only declared if 'needTempVarForGet' is set,
and it should be set when we have a MEMBER property.
