Dragging map on mobile triggers SelectFeature

[allesmi]

Suppose you have a map with a background layer and a WFS feature layer.

In a desktop web browser it is possible to click on the feature to trigger the SelectFeature handler as well as starting to drag the map without calling the handler.
On mobile a drag always triggered the SelectFeature handler.

Investigating the issue we found out that the event is triggered at touchstart.

We worked around this issue by replicating the behaviour of another OL component where we evaluate at touchend if it is a click or a drag.
