Last opened page feature doesn't work if last page was a subpage

[Jeremy Bícha]

Impact
-------
GNOME 3.28 added a new feature that shows the last opened page when opening GNOME Settings (gnome-control-center). Due to a leftover from the previous design (before GNOME 3.26), this feature did not work correctly in all cases.

It would work if run from the command line.

It would not work if the last opened page was a subpage in the Details or Devices section and GNOME Settings was opened from the GUI (since that uses the .desktop).

Test Case
---------
1. Open Settings to the Details > Users panel.
2. Close Settings
3. From the Activities Overview, open Settings

Settings should open to the Users panel.

Regression Potential
--------------------
None. This is a simple bug fix to get the intended behavior in all situations

This bug was fixed in the package gnome-control-center - 1:3.28.1-0ubuntu2

---------------
gnome-control-center (1:3.28.1-0ubuntu2) cosmic; urgency=medium

  * Rename ubuntu-gnome-version.patch to distro-logo.patch for proposed
    upstreaming to Debian. Drop the hardcoded use of the Ubuntu font.
    (LP: #1770473)
  * debian/control.in:
    - Drop now unnecessary fonts-ubuntu dependency
    - Don't recommend libnss-myhostname since systemd-resolved handles this
      functionality (LP: #1766575)
    - Demote network-manager-gnome dependency back to recommends
      (LP: #1770673)
    - Depend on system-config-printer instead of system-config-printer-common
      for the Additional Printer Settings button (LP: #1770695)
  * Add 0007-fix-open-last-page.patch:
    - Proposed patch fixes the "open last opened page" feature for Devices and
      Details pages (LP: #1770699)
