Add types to some no-type tokes in js.wy

Add types to some no-type tokes in js.wy

* admin/grammars/js.wy: Add types to the FALSE, TRUE and QUERY tokens.

Without the types, you'd get the warning

*Warning* default value of <<no-type>> tokens changed to QUERY, was NULL_TOKEN
*Warning* default value of <<no-type>> tokens changed to TRUE, was QUERY
*Warning* default value of <<no-type>> tokens changed to FALSE, was TRUE

I think this should be harmless, and it doesn't seem to break handling
.js files.
