app_mp3: Throw warning on nonexistent stream

Currently, the MP3Player application doesn't
emit a warning if attempting to play a stream
which no longer exists. This can be a common
scenario as many mp3 streams are valid at some
point but can disappear at any time.

Now a warning is thrown if attempting to play
a nonexistent MP3 stream, instead of silently
exiting.
