Open the update-rc.d manpage, search for 'disable' and it says:
A common system administration error is to delete the links with the thought
that this will "disable" the service, i.e., that this will prevent the
service from being started. However, if all links have been deleted then the
next time the package is upgraded, the package¿s postinst script will run
update-rc.d again and this will reinstall links at their factory default
The correct way to disable services is to configure the service as
stopped in all runlevels in which it is started by default. In the System V
init system this means renaming the service¿s symbolic links from S to K.
You didn't disable network-manager. You removed the startup scripts which were
correctly put back by the update.
Of course I only know this by being bitten by it several times in the past ;-)
