I agree that this is a bug.

But I don't agree with this fix, as it will cause upgrades to always
enable the module, even if was previously disabled by the system
administrator. I don't see OTTOMH what the correct fix is, although I
expect that it will be easily discovered by looking at similar postinst
scripts.
