Fetch completion info from user progress bloc

[JElgar]

Description

Currently we store completion info inside resource models. This make its pretty hard to update after users complete more stuff which is what #350 is about. This pulls all completion/joined data from user progress bloc which is updated after each resource is completed and is therefore easy to keep up to date.

Fixes #350
