ExploreMapFragment.java: remove method call that causes recursive loop

Before this commit, there was a call loop that included onScroll and animateTo
on the map. These two method calls caused performance issues in
ExploreMapFragment.

This commit breaks the call loop by removing moveCameraToPosition from getMapCenter.
Also, the removed code did not fit the purpose of getMapCenter.
