Fabian Homborg 60248e895f Use __fish_complete_user_at_hosts
for various completions.

This makes the code a bit nicer, removes one of the
__fish_print_hostnames calls (which are slow) and a sed call, thereby
improving performance by about 33% (600ms to 400ms).

Fixes #4511.

function __scp2ssh_port_number

# for specifying the TCP port number. This function deals with that by extracting the port
