Update dsr.ts DSR using params subset redirecting to the default state

[DavideCordella]

Dear All,
I have one root state with a parameter and two substates with the following config:
rootState1, /rootstate1/:rootstate1param, params: [rootstate1param]
rootState2, /rootstate2/:rootstate2param
sub1, rootState1.sub1, /sub1, default
sub2, rootState1.sub2 /sub2/:sub2param

The DSR on rootState1 is configured to consider only rootstate1param.
If I first access sub1 state and then sub2 when I switch from rootState1 to rootState2 and I come back to rootState1 I get redirected to sub1 instead of sub2 like I'd expect being the last accessed state.

I think the issue is in the following function:

DSRPlugin.prototype.recordDeepState = function (transition, state) {

     var _this = this;
    var $state = this.$state;
    var hasParamsConfig = !!this.getConfig(state).params;
    var _state = state.$$state();
    transition.promise.then(function () {
        var transTo = transition.to();
        var triggerParams = transition.params();
        var target = $state.target(transTo, triggerParams);
        var targetStateName = target.name();
        var targetParams = target.params();
        var recordedDSR = { triggerParams: triggerParams, targetStateName: targetStateName, targetParams: targetParams };
        if (hasParamsConfig) {
            var currentDSRS = _this.dataStore.get(_state);
            var predicate = _this.paramsEqual(transTo.$$state(), triggerParams, undefined, true);
            var updatedDSRS = currentDSRS.filter(predicate).concat(recordedDSR);
            _this.dataStore.set(_state, updatedDSRS);
        }
        else {
            _this.dataStore.set(_state, [recordedDSR]);
        }
    });
};

the problem is at following line:
var predicate = _this.paramsEqual(transTo.$$state(), triggerParams, undefined, true);

insted of passing undefined as 3rd param of paramsEqual we should pass this.getConfig(state).params

Shall I forward a pull request in order to have it fixed???

Many thanks everybody.
