Fix background mode initialization on client tty frames (rep. by Dan Nicolaescu).

lisp/server.el (server-process-filter): Add the client parameter to
the initialization parameters of new frames.
(server-getenv): Use the 'client frame parameter and not
server-clients-with to get the client; server-getenv is called during
frame initialization. (Dan Nicolaescu)
