Before the refactoring of callObjectPropertyLookup and
initCallObjectPropertyLookup this was done via a check on the resulting
function. This check is in the init method now. However, after
initialization, you can still call the (pre-resolved) method on a nullptr.
Therefore, we need a second check.
The method counts as pre-resolved even if we re-fetch it due to a
variant lookup. We can be sure that there is some method in that case
after all.
