Manage Account Artifacts list does not display claimed artifacts

[lauratinnel]

Describe the bug
I first noticed that the artifacts list under Manage Account does not match the list under My Artifacts (discrepancy).

On examination, it appears that the Manage Account list includes entries only for edited (revised) objects but not claimed artifacts.

Now that we have the My Artifacts list on the left side, it's not clear what the purpose of this list is. Same thing with favorites. We might consider just deleting these two here. That would leave just the ratings here, but we might consider moving ratings to the left menu as well so everything is consistent. That would leave Manage Account to just .... managing the account/profile.
