Bug#757818: partman-lvm: Refuses to reinstall if it find old lvm volume

[Petter Reinholdtsen <pere@hungry.com>]

Control: tag 757818 + patch

I've tested both '--yes' and '--wipesignatures n' in d-i now, and both
work.  With either, I am able to reinstall a Debian Edu profile
without any problem. :)

I am not quite sure which of these best fit d-i.  I notice the Fedora
people went with --yes in anakonda.  Perhaps we should do the same?
On the other hand, the old behaviour was to not wipe signatures, and
to keep it we should add '--wipesignatures n'.

Based on this, I recommend we use '--wipesignatures n' to keep the old
behaviour.  Here is a patch implementing the fix.
