Tap and hold ending outside of LifeLine crashes the app

[Cécile Camillieri]

• In MessageView view, tap and hold on a LifeLine
• Before the bar fills up, slowly move a bit right or left outside of the LifeLine (see attachment)
• When the TapAndHoldEvent is finally processed the app crashes as follows:

Exception in thread "Animation Thread" java.lang.IndexOutOfBoundsException: Index: 1, Size: 0

It probably happens because the app looks for a LifeLine at the location where the event ended, and not where it started.

Looks like a bug in MT4j to me, because the "end point" when the tap-and-hold is complete should be the same as the start point. So we can either work around it in TouchCORE, or change that code in our version of MT4j :)

Resolves #303: tap and hold get location method changed by getCursor().getStartPosition()
