<ion-searchbar> (ionClear) is calling twice

Original issue by @Bloggerschmidt on 2017-01-11T14:13:22Z

Ionic version: (check one with "x") [ ] 1.x [x] 2.x

I'm submitting a ... (check one with "x") [x] bug report [ ] feature request [ ] support request => Please do not submit support requests here, use one of these channels: https://forum.ionicframework.com/ or http://ionicworldwide.herokuapp.com/

Current behavior:

Clicking the clear button in <ion-searchbar> (the x at the end) (ionClear) is calling a function twice (for the event types 'mousedown' and 'click').

Expected behavior:

(ionClear) should call only once (for event type 'click' or (!) 'mousedown')

Steps to reproduce:

ionic start --v2 myApp blank
