TIMOB-9913 Android: Remove the unused references to Map View's "animate" property.

See [Testing Notes in JIRA](https://jira.appcelerator.org/browse/TIMOB-9913?focusedCommentId=267199&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-267199).

The "animate" property of a map view was listed
in documentation as being supported by Android.
However, it is never accessed anywhere in the code --
it is only set and never read. It cannot be supported
since it clobbers the animate() method of the view.
