tab-completion for grub-set-default suggests wrong id for kernel

[Hanno]

When using grub-set-default, it offers tab-completion on the command line.

On my system, entering "grub-set-default" and then pushing tab twice will result in a list of possible kernels, e.g.

Ubuntu, with Linux 3.12.0-rc7-custom
Ubuntu, with Linux 3.19.0-23-generic

Ok, so let's use on of these:

grub-set-default "Ubuntu, with Linux 3.19.0-23-generic"

That won't work. Instead, "update-grub" will complain:

Generating grub configuration file ...
Found linux image: /boot/vmlinuz-3.19.0-23-generic
Found initrd image: /boot/initrd.img-3.19.0-23-generic
Warning: Please don't use old title `Ubuntu, with Linux 3.19.0-23-generic' for GRUB_DEFAULT, use `Advanced options for Ubuntu>Ubuntu, with Linux 3.19.0-23-generic' (for versions before 2.00) or `gnulinux-advanced-956a13ed-762e-4b00-8688-67f6339d5c37>gnulinux-3.19.0-23-generic-advanced-956a13ed-762e-4b00-8688-67f6339d5c37' (for 2.00 or later)

done

So if tab-completion is suggestion the wrong title, it should be fixed.

This bug occured on Ubuntu 15.04 with grub2-common 2.02~beta2-22ubuntu1.1
