Better error handling for errors on home page rows (#1128)

## Description
Adds better error handling when loading home page rows. For example,
this fixes loading errors if a playlist row is configured, but the
playlist is deleted.

Also fixes an issue from #1116 where changing users doesn't go the home
page.
