**Current behavior:**
When you have one <ion-slide> inside another, the length() of the parent one is wrong, the length() is returning the sum of all slides (parent and children)

**Expected behavior:**
The parent slide should return only it's own count of slides.

**Steps to reproduce:**
Open the plunkr, and click on the button "Check length", the length must be 4 but it is 16.
