FIX: prevents errors on /tags when a tag `constructor` exists (PR #10449)

This is due to js objects having a constructor property:

const obj = {};
obj['constructor'] // return [native code] and not undefined

Technically only the js code is necessary, but I think having this as a reserved tag is probably safer.
