Restart CLI server too when restarting query server

[edoardopirovano]

Closes #1486

@aschackmull encountered a bug where after he'd rebuilt his CodeQL dist, he did Restart query server so was running with a new query server, however was still using an old CLI because the CLI server had not been restarted. This led to a bug because the old CLI did not understand the evaluator logs produced by the new query server. The solution, I think, is for the extension to also restart the CLI server when it restarts the query server in order to ensure they are the same version.
