faces.js handing of params attribute missing in the old jsf.js codebase

In reference to https://issues.apache.org/jira/browse/MYFACES-4040

We have had a spec deviation from the spec since jsf 2.0

apparently request parameters must be passed in the options associative array under the key params (see link above where I documented it)

This already has been fixed in the new typescript codebase but the fix is missing from the old javascript codebase. 

The fix is fairly straight forward.

For now we will keep the old behavior, to keep legacy code intact, but the f:params renderer also must be adapted accordingly.

Either I will do that or someone else.
