Unregistering Palm conduit fails if Hotsync Manager not installed

[Lance Edgar]

Apparently if Hotsync Manager is not installed, you can't really unregister the Rattail Palm conduit. That probably is never going to be a significant problem in the real world, but nonetheless it would be nice to handle the exception and show something nicer to the user.

Fixed in 317d33b/rattail. It's possible there are still some logic paths which aren't handled, but the simple case of Hotsync Manager not being installed should be okay.
