Update Rocket to latest version

Rocket requires nightly, but on nightly 2017-12-13 and after
the version of Rocket juniper's integration was using wouldn't
build. This is solved by updating Rocket to `0.3.4` which
according to the [changelog](https://github.com/SergioBenitez/Rocket/blob/v0.3.4/CHANGELOG.md#version-034-dec-14-2017):

"Codegen was updated for 2017-12-13 nightly."
