QObjectPrivate::Signal: initialize all members
requested to merge asturmlechner/qtbase:asturmlechner/QObjectPrivate-Signal-init-all-members into kde/5.15
A recent change in that area triggered Clang-SA to rescan the code and
complain about this pre-existing bug: If receiver == nullptr, then the
previous member was never initialized.
Fix by null'ing it using NSDMI. This is a trivial type, the compiler will be able to avoid the redundant write.
