The `_platforms` array wasn't being populated on provider instantiation. Added the appropriate code to populate the array so that when we use other functions from the provider, we get the correct data in return.

* fix(item-sliding): update item options to show border
- show the border on left options only if in a full list

default)

also renames isRightSide to isEndSide to match the side values
