TreeView's observers will be called when the selected domain object changes, which can occur for one of two reasons: 1. Because a new value was set externally, from mct-tree. 2. Because a new value was selected, by the user. In the latter case a $apply is needed, but in the former it is not (and causes an error.) However, when that case occurs, the value in scope will be up to date already (it was a watch that triggered the call to treeView.value) so no assignment or $apply is necessary. Fixes #1114.
