Under 1.25, using the local provider, I was able to reproduce the
behavior.  On the  and even got the same confusing log entry:

  2016-05-09 16:48:51 DEBUG juju.cmd.jujud machine.go:1741 uninstall
file "/var/lib/juju/uninstall-agent" does not exist

So it's not readily apparent what is deleting the files and removing
the init services.  However, it *is* happening.
