Fix lookup of enums declared in QML singletons
Given the following expression
var x = MySingleton.MyEnumValue
where MySingleton is a QML (composite) singleton and MyEnumValue comes
from a QML declared enum, we had code in place up to (and including)
5.10 to attempt to optimize that expression to a enum constant at
compile time. In 5.10 that optimization does not exist anymore. In <=
5.10 we would also skip the optimization under certain circumstances
(too many statementes, etc.). The fallback that is in place for handling
this at run-time tried to be smart by avoiding the
QQmlContextWrapper::get lookup and return straight a reference to the
singleton as QObject. That works for regular property lookups, but it
fails when trying to look up something like an enum, that isn't a
meta-object property.
