Don't create a .directory-file for each directory

This regression has been introduced on master and has not been
released yet: Due to the changed properties-format an update has
been done which resulted in writing a .directory file into each
newly entered directory.

The patch updates the view-properties and version only in the
constructor so that it is assured that reading properties never
accidently will change the internal version.

A unit-test has been added to catch regressions like this in future.
