jsonfilter and queries with '-' in them

it is basically mimicking JavaScript object access syntax where labels after a
dot must be valid identifiers.

In JS, an expression `obj.foo-bar.baz` would be interpreted as `obj.foo` minus
`bar.baz`. The jsonfilter grammar simply followed this rule even if its
current expression syntax scope would allow for tolerating such a ambiguities.
