Make server start more robust

The present configuration is supposed to start the server if it's not already
running.  Previously we checked this using `server-running-p', but this is not
really realiable.  Instead, we now checking the `server-process' variable
directly.

Furthermore, if it turns out during startup that the currently configured server
file is already present, we warn the user about this and don't do anything
else.  We let the user to fix it manually because it's (i) easy for the
user (easier than doing it automatically) and (ii) only done once, namly during
startup (the burden on the user is thus tenable).

The current implementation may not be accurate, though, as my understanding of
the implementation around Emacs' server functionality is only at the beginning.
