Issue #1551: 'svn log' handles unversioned targets poorly

Since the log subcommand cannot properly support multiple WC targets
currently, there is no reason why it should not error out when passed
an unversioned WC path.  When log is fixed to handle multiple WC
targets, this can be revisited.

* subversion/libsvn_client/log.c
  (svn_client_log2): Return an unversioned resource error if the sole
    WC target passed is not found in the entries file.
