systemd-resolved constantly restarts on Bionic upgraded from Xenial

Bug description:
[Impact]
Log noise due to needless restart of resolved on lease expiry, maybe loss of
cached state?
[Test case]
(1) Append make_resolv_conf to the end of the file, so it gets executed
(2) Execute the file with bash -x and different settings and ensure there are
no restarts if the settings are the same, and that there are if settings
change; for example:
sudo new_domain_name_servers=8.8.4.4 interface="wlp61s0" reason=REBIND bash
-x debian/extra/dhclient-enter-resolved-hook
sudo new_domain_name_servers=8.8.4.4 interface="wlp61s0" reason=REBIND bash
-x debian/extra/dhclient-enter-resolved-hook
=> no restart
sudo new_domain_name_servers=8.8.8.8 interface="wlp61s0" reason=REBIND bash
-x debian/extra/dhclient-enter-resolved-hook
=> should restart
sudo new_domain_name_servers=8.8.8.8 interface="wlp61s0" reason=REBIND bash
-x debian/extra/dhclient-enter-resolved-hook
=> no restart
sudo new_domain_name_servers=8.8.4.4 interface="wlp61s0" reason=REBIND bash
-x debian/extra/dhclient-enter-resolved-hook
=> should restart
[Regression potential]
The change only restarts resolved when the settings change. If there's a bug
in the logic, resolved might not be restarted when it should be. Also, since
there will be less restarts of resolved, it will run longer, so if there are
memory leaks they will become more apparent.
[Original bug report]
If a cloud server is upgraded from Xenial to Bionic, the dhclient system
remains in place and any DHCP lease refreshes cause a needless restart of the
system-resolved daemon
