This prevents a stack trace that is shown in the logs when the stream manager is
released after the activity was stopped. In this case the call to
`streamManager.destroy()` coming from `releaseSourceInternal()` of the media
source is too late and produces an error saying `Application attempted to call on
a destroyed WebView`. The error has no effect but it's nice to not have this
stack trace in the logs.
