Check put before get get next

[mblaney]

When get is chained, eve.put['.'] contains the lex match and eve.get contains the parent get, so need to match put first. Given the following example this matches alice instead of friends:

(async () => {

var alice = await SEA.pair();

const gun = Gun();

await gun.user().auth(alice);
    
let userNode = gun.user().get('friends');
userNode.put({
  "alice": {
    parent: false
  },
  "bob": {
    parent: false
  },
  "carol": {
    parent: false
  },
});

setTimeout(() => {
  gun.user().get('friends').get({'.': {'>': 'aaron', '<': 'ben'}}).once().map().once(console.log);
}, 2000);

})();

This only works in the example because there's a put before the get, so closing this pr for now. :-(

Need to work out why chained gets don't pass on the key to match against lex.
