Remaining instance of "directory server"

[pljones]

In the translations, I've spotted the following:

        <location filename="../serverdlg.cpp" line="737"/>
        <source>Now a directory server</source>

The "Now a directory server" may be the last remaining instance of "directory server" usage - there should be none left.

To Reproduce

Look at serverdlg.cpp line 737.

Expected behavior

Should say Now a directory.
