Update uiSref input type to match functionality

[oBusk]

Was updating our code to try to use strict templates and was noting failures on templates that has been working for years. Noticed that the inputtype to uiSref is "string" when it works just fine with a declaration or object too, since the internal uses all support StateOrName.

Should this be changed on line 125 too?

[oBusk]

I'm confused? L125 in this file?

angular/src/directives/uiSref.ts

Line 125 in a34d95a

@Inject(UIView.PARENT_INJECT) parent: ParentUIViewInject

[christopherthielen]

oops, typo. I meant Line 135

  /** @internal */
  set uiSref(val: string) { // here
    this.state = val;
    this.update();
  }

Hmm I suppose so? But I can't really find anywhere this internal method is being used tbh? Was thinking it was for testing or maybe something angular-hybrid does, but I can't find anywhere we're uiSref is given a value on the class directly

I do believe the setter is how the data-binding is applied

  @Input('uiSref') state: StateOrName;

[oBusk]

Hmm well the decorator should bind the directive input "uiSref" to the class property "state". But nevertheless, whatever it's use, the setter should have the same type as the value it sets, I've updated it.
