Ne need to pending sticky events until buffer is coming

Thanks for your comment.
As I mentioned before, I use the funnel element for supporting internal
subtitle contents.
My Pipeline is likes this.

            /  input-selector  - audiosink
uridecodebin -  input-selector - videosink
             `- funnel - streamiddemux - appsink

For example, if no data was received or data feeding is late, sticky events can
be pending continuously. And streamiddemux only receive gap event continuously.
Thus, pipeline can not be constructed completely.
I think that if there is one sinkpad in funnel, no need to pending sticky
events until data is coming.
Please review and check my patch and you want me to do with unit test, I will
do.
