Cloning into existing dir does not update annotation in tree view

[bpoldrack]

Cloning and selecting a target path in the widget implies, that we clone to an existing directory (since the directory path selector does not allow to give a not yet existing path). That does not trigger an annotation update in the tree widget. Since by default we have sorting by Type in the tree view, one would expect a new clone to show up at the top alongside other directories of type dataset. That does not happen.

Reproduced on a mac, for both create and clone.

Reproduced on Windows for create

Similarly, cloning does not work when designating the folder path, however no problem if path not specified.

After updating to datalad==0.17.6, the create operation works as expected here.
