ui: only use "user@host" as username in noninteractive mode

We regularly see people on IRC ask how they can correct commits they
accidentally made without having configured a username. This change
will make Mercurial abort when a commit is made without a username.

If Mercurial is run without a TTY (from a cronjob or similar), a
username is constructed as usual. Schematically the changes are as
follows:

With ui.askusername=False:

                  old         new
  interactive     user@host   abort
  noninteractive  user@host   user@host

With ui.askusername=True:

                  old         new
  interactive     prompt      prompt
  noninteractive  user@host   user@host
