Masayuki Nakano 00b602a0f0 Bug 1627673 - Do null-check the result of DragEvent::GetDataTransfer() in EditorEventListener` r=smaug
I guess that `DataTransfer::HasType()` is inlined in the opt builds and
actually crashed in `EditorEventListener::DragEventHasSupportingData()`
at accessing `aDragEvent->GetDataTransfer()` result without null-check
because `DataTransfer::mItems` is set to `nullptr` only by the cycle
collector, but it does not make sense to think that it occurs the STR
in bug 1627673 comment 3.

Therefore, this patch adds null-checks in
`EditorEventListener::DragEventHasSupportingData()`.

I have no idea how to test this with automated tests.
