mod_http_oauth2: Improve error messages for URI properties
Since there are separate validation checks for URI properties, including
that they should use https, with better and more specific error reporting.
Reverts 'luaPattern' to 'pattern' which is not currently supported by
util.jsonschema, but allows anything that retrieves the schema over http
to validate against it, should they wish to do so.
