Connection to server defined by command line options always uses more than one connection

[Manfred Luetkenhaus]

When the client is started automatically from another program, using command line options to specify the server, the client will not limit the number of connections to 1.
When connected to a server that supports only 1 ftp connection at a time, no file transfers are possible.

This worked in client V2.2.32 (but this older version had other issues).

When i use the ServerManager as a test, i can limit the number of
connections to 1, then everything works, but this is not a solution, i cannot use the ServerManager for all possible automatically connections.
