Keep strong references to Picasso notification icon loading targets

Browse Source 
Before the Target would sometimes be garbage collected before being called with the loaded channel icon, since Picasso holds weak references to targets. This meant that sometimes a new streams notification  would not be shown, because the lambda that should have shown it had already been garbage collected.
