SLURM: fix the queue info command

The queue info command for the SLURM batch system was outputing an
asterisk (indicating a default queue) that was not getting parsed.

From the sinfo man page: http://slurm.schedmd.com/sinfo.html

%P - Partition name followed by "*" for the default partition ,also see %R
%R - Partition name, all see %P
