AVFoundation: fix playback of files with spaces in their names

Used QUrl::toEncoded() instead of QUrl::toString().

Usage of QUrl::toString() leads to URLs which can contain spaces and as
result such URLs are not accepted by AVPlayer, and it remains in unknown
state because AVFMediaPlayerSession::processLoadStateChange() is not
called at all. And as result, QMediaPlayer waits media loading forever.
