Possible real fix as described in bug #1479001

This change has the side effect (a regression) of making it impossible
to sideload an older version of a click, since the system hooks are run
on boot: the older versions will be unregistered upon the next boot. We
believe this is fixable by comparing the timestamps of a user's
registrations with the newer version of the click included in the OTA
update, and only unregister if the user's registration is older than the
OTA update's.

Unfortunately, that hits another issue where the user registrations
timestamps seem to get updated upon every reboot, which means they'll
always be newer than the OTA update's. We believe we can resolve this by
making the user hooks a little smarter about touching registrations that
don't need to be touched, but it still requires a bit more
investigation.

Title:
  'Latest' version of a click package used after reboot

Status in Client Developer Experience:
  Confirmed
Status in click package in Ubuntu:
  Incomplete

Bug description:
  The 'latest' version of a click package is used after a reboot, even
  when a click with a lower version has been manually installed.

  What happened:
  1) Install a click packages for an existing application with a lower version than that of the preinstalled one
  2) Launch the app and notice that the newly installed is launched
  3) Reboot the device
  4) Launch the app and notice that the preinstalled one is used due to it having a higher version

  What was expected to happen:
  At step 4) for the manually installed version of the click package to still be the selected one

  
  This affects the developer experience for example, when working on the bgplaylists of the music-app the branch has a lower version (bzr rev) than trunk/what is in the store, and after installing new versions of media-hub to test the device must be restarted. So after each restart the developer must also remember to reinstall the click package.
