Fix an assertion failure when updating a symlink. The client's method of
determining whether an incoming file is a symlink was faulty.
Reported by: Søren Thing Andersen
(update_symlink): New test. Triggers an assertion failure with 1.7.0.
(close_file): If the status of a symlink doesn't change, the server
won't send a property change, so don't expect to see a property change
for svn:special if the update doesn't change the property.
Also, correctly handle incoming deletion of svn:special, in which
case the server sends a NULL value for svn:special.
