No cache / time of last update not taken into account

[Letterus]

What Happened?

AppCenter looks for updates too often. That leads to an annyoing experience.

Steps to Reproduce

1. Start AppCenter. Overview is showing the "Check for updates" spinner.
2. Wait for the task to complete.
3. Click the "update" icon: AppCenter starts to check for updates again, don't showing me the results of the last check. So I have to wait again.

This may be repeated for every start of the app.

Expected Behavior

Only check for updates once upon a time and cache that result for 2 to 24 hours. Suggestions: 24h on stable, 8h on RC, even less (2h?) on daily.
