Bug description:
  [Impact]

  If one deselects all packages, the "Install Now" button disappears,
  which makes sense (on another note it would make even more sense if it
  was simply grayed out). However when one or more packages are then re-
  selected, the button won't ever reappear, and update-manager must be
  restarted in order to upgrade any packages.

  [Test case]

  For each affected $series:

  * If 'apt list --upgradable' is empty, downgrade any one package in your system.
  * sudo ua detach --assume-yes
  * sudo apt install hello
  * update-manager
  * Verify at least one update is available, and the hello package is unavailable under the 'Ubuntu Pro security updates' section
  * De-select all available packages
  * Verify the 'install now' button disappears
  * Select at least one available package
  * Verify the 'install now' button is still absent
  * Close the window

  * Enable proposed (see https://wiki.ubuntu.com/Testing/EnableProposed)
  * sudo apt install -t $series-proposed update-manager

  * update-manager
  * Verify at least one update is available, and the hello package is unavailable under the 'Ubuntu Pro security updates' section
  * De-select all available packages
  * Verify the 'install now' button disappears
  * Select at least one available package
  * Verify the 'install now' button is now visible again

  [Where things could go wrong]

  Things could go wrong with the 'install now' button. It should be
  visible when there is any available package selected and not visible
  when there is none selected. So a regression could appear as the user
  no longer being able install packages via this program, or being able
  to click "install now" with no packages selected to be installed. In
  any case, since this program is essentially a wrapper of Apt, all the
  package management functionality, including upgrading, would still be
  avaialable through Apt.
