* RESTCONF in Clixon used empty key as "wildchar". But according to RFC 8040 it should mean the "empty string".

Browse source 
* Example: `GET restconf/data/x:a=`
  * Previous meaning (wrong): Return all `a` elements.
  * New meaning (correct): Return the `a` instance with empty key string: "".
* [RESTCONF GET request of single-key list with empty string returns all elements #213](https://github.com/clicon/clixon/issues/213)
* [RESTCONF GETof lists with empty string keys does not work #214](https://github.com/clicon/clixon/issues/214)
