Reload tiles when adding a tree
Reload tiles when adding a tree

A regression occurred when adding map features. The main issues is that
the geo rev count is updated by a database trigger, thus invalidating
any existing objects. Since we want to return the update geo rev, we
need to requery the instance.

Fixes #1152
