Find translation usages that are missing params

[runspired]

Since formatjs requires that any context param must be present even if undefined we should ensure the param is always provided to the helper.

e.g.

{
  "a.key": "something {aParam}"
}

{{t "a.key"}}

Should produce an error reportable by this tool
