Bug#244977: auto-partition wipes out existing NewWorld boot partition if created in the same session

["Dave Miller" <justdave@bugzilla.org>]

Package: partman-auto
Version: 15

steps to reproduce:

1) Choose auto-partition
2) write partition map
3) get yelled at because there's no NewWorld boot partition (see bug 243253)
4) go back to the partition map
5) delete the new ext3 and swap partitions
6) choose FREE SPACE
7) select Create a new partition
8) set size to 820K
9) set usage to Use as NewWorld boot partition
10) choose "Done setting up"
11) choose FREE SPACE
12) choose auto-partition

Actual results:

partition map now shows the former NewWorld boot partition as "do not use"
instead of "boot"

Expected results:

the NewWorld boot partition should still be intact
