Enable asset retrieval in javalab local mode

[molly-moen]

Javabuilder is being updated to allow for programs to retrieve assets (images, audio) from the assets system (See this PR. This PR updates the local setup for the Javalab connection to Javabuilder to include the channel id needed to generate the asset urls. The non-local version already has this information.

The update linked above also removes the need for the projects url to be passed. Removed this on the local side here (and therefore this should be merged after the Javabuilder PR), and put a note to remove it on the session token side once Javabuilder has been deployed with the updates. Removing it from the session token now could cause Javabuilder to break if we do things in the wrong order.

LGTM - I know there's some more conversation on the JavaBuilder side on how this should work, but for local testing this seems fine
