test application

I tried adding gst_tee_src_getcaps() to tee. Similar to what Wim did in Bug
#316248 for adder. It does not show obvious improvement though :/ I also tried
to keep a copy of the peercaps and taking shortcuts it they have not changed.
Unfortunaly I still need to request them that for and thsi triggers the
machinery ...

I belive the main issue is that _getcaps() is called so many times:
5 x for tee:src0
8 x for tee:src1

I also wonder why gst_pad_proxy_getcaps runs 3 times for tee:sink.
