bump go-libp2p dependencies in pubsub test

[yusefnapora]

This bumps us up to go-libp2p v0.9.0 for the pubsub test - I was getting a build error with 0.6.1 due to some api changes in swarm.

oh dear... with the updated deps I'm getting failures:

@raulk / @aarshkshah1992 have you guys seen any latest peer record does not exist errors with go-libp2p 0.9.0? Am I possibly missing a dependency somewhere?

[aarshkshah1992]

@yusefnapora This should now be fixed. Please can you close the issue if you are happy ?
