Slow to start when many updates available

[Robert Ancell]

[Impact]
GNOME Software is slow to show anything when updates are available due to downloading Changelog information.

[Test Case]
1. Open GNOME Software when you have many updates to make and/or a very slow connection to changelogs.ubuntu.com

Expected result:
The home screen is quickly shown

Observed result:
The home screen takes many seconds to show

[Regression potential]
Low. We now just download these on demand.

Solved by making the changelogs download on demand.
