Enyo-56: change DataRepeater to be able to catch event from it's items

## Issue 
DataRepeater loses ontap events(even all of events)

## Cause
Usally, owner of DataRepeater items aren't DataRepeater, owner of DataRepeater items are same with DataRepeater's owner. And owner of components in the item is just the item.  
As a fix for an issue(http://jira2.lgsvl.com/browse/GF-35208), comparison code is inserted in dispatchEvent function. That code are checking whether event originator's owner is same with this or not.  
After that fix, events from the components in the item can not handled properly

## Fix
Unlike the 2.3.0-rc, getBubbleTarget function in 2.5.0 are checking event.delegate and returing owner directly(it can solve previous issue - http://jira2.lgsvl.com/browse/GF-35208)
So, I removed owner of comparison line to be able to handle event which is from the item
