initial script directory is always /root

The reported problem is fixed: we change to the user directory if it exists, or change to / (as login does).

- self.process_factory.spawnProcess(pp, filename, uid=uid, gid=gid)
+ self.process_factory.spawnProcess(pp, filename, uid=uid, gid=gid,
+ path=path)

Via experimentation, I ended up as a regular user inside /root under these conditions:

- /home/andreas is for some reason unreachable (I used 0000 for /home/andreas to see what would happen)
- /root is 0700, owned by root:root

The script I asked to run as andreas is:
id
echo "pwd = $(pwd)"
ls -lad /home/andreas /root

And this is the response:
uid=1000(andreas) gid=1000(andreas) groups=4(adm),20(dialout),24(cdrom),25(floppy),29(audio),30(dip),44(video),46(plugdev),107(fuse),111(lpadmin),112(admin),1000(andreas)
pwd = /home/andreas
d--------- 2 andreas andreas 4096 Jun 11 11:47 /home/andreas
drwx------ 4 root root 4096 Jun 13 12:05 /root

The desired response would be to run the script in "/" in this case.

Never mind the previous posting, it actually ended up inside /home/andreas and worked as expected. For some reason I thought it ended up in /root again.

Thanks very much for refactoring test_user.

+ return self._run_script("user", 1234, 5678, "/")

There's an extra space between 'return' and 'self._...'.
