Don't iterate over the connections without holding a lock
When checking whether a slot is connected to a signal, we need to
hold the signalSlotLock to be sure about the answer, or we can
get crashes when a connection gets removed while doing the check.
The check in activate() can handle some uncertainty as it's only
a shortcut to the longer path.
Fixes: QTBUG-74604
