parsebin: Don't store bogus caps on GstStream

If we can't get the current caps when receiving a stream-start, that's fine,
they can/will be provided by other means at a later time.

What we definitely should not do is provide the starting caps of the chain,
which are potentially completely different from the end ones (like for example
`application/x-rtp`)
