    directory: Fix search for other homeservers
    
    The matrix server request expect the "server" parameter to be a string.
    If the "server" in Parameters is "Option<Host<String>>" it serializes to
    somethign like 'Domain("matrix.org")'.
    
    This patch makes the server parameter a string so the request is built
    correctly everytime. The "Host" enum is converted to an string during
    the parsing.
