[Regression] Warning: QObject::connect: invalid null parameter

[ezavod]

I am getting an error: :0 : Warning: QObject::connect: invalid null parameter on startup.
This is consistently reproducible since 7e3ad7b.
As far as I can tell the problem seems to be that av is null in lines 237-238 in above mentioned commit:

    CoreAV* av = core->getAv();
    connect(av, &CoreAV::avEnd, this, &Widget::onCallEnd);

I think this is because Core::getAv is called before Core::start initializes the returned av.

I couldn't reproduce this on tip at the location mentioned, but

qTox/src/widget/widget.cpp

Line 240 in c499597

CoreAV* av = core->getAv();

is definitely null at connect time and throwing the same error.
