deploy: Correctly swap bootloader version with new boot checksums

Browse Source 
If we had two deployments with different boot checksums, and were
trying to remove the one that was the same and add a new one (the
normal case), we'd end up assuming due to comparison with 0 that
we only needed to do the fast subbootversion swap.

Fix this by actually putting 1 where we really mean 1.

And update the tests to verify the fix; I have double-verified by
undoing the fix, and noting that the test fails.
