AppCenter installs phased updates even if they are held back

[TomiOhl]

What Happened?

Meet Ubuntu's phased updates: https://askubuntu.com/questions/1431940/what-are-phased-updates-and-why-does-ubuntu-use-them
When the updates are kept back for a package, Appcenter shouldn't even show them. The current behavior defies the meaning of phased updates.

Steps to Reproduce

1. update packages in terminal via sudo apt upgrade
2. you may notice that the output says some packages are kept back, so they weren't installed
3. open AppCenter and check for updates
4. AppCenter will show those kept back packages and you will be able to install them

Expected Behavior

Kept back updates shouldn't be shown in AppCenter.

OS Version

7.x (Horus)

Software Version

Latest release (I have run all updates)

I believe this is an issue with packagekit which appcenter uses, because if I run pkcon refresh and pkcon update in the terminal it goes ahead and installs the updates which are supposedly held back as reported by apt.
