Unset QtCamdevice viewfinder when Viewfinder is being destructed.

This fixes the following crash:
pure virtual method called
terminate called without an active exception
Aborted

Viewfinder was being destroyed and QtCamDevice was still holding a pointer
to garbage. It tries to stop viewfinder when the device gets stopped
which leads to the above mentioned crash.
