Allow play stats for artist

[robbevp]

Allow the user to see their play stats per artist.

The layout of the stats page stays the same, just with filtered plays/tracks. Plays are currently only filtered based on the track_artists.

To access this page, I added a stats icon to the ArtistActions. I'm unsure if this needs to be shown in both the card and on the artist page, both left it like this for now.

Some screenshots showing all visual changes:

I would not show this on the card. It's not that much of a primary action, IMO.

I've updated this to only show the stats button on the artist's page

I get the following warning in the console:

[Vue warn]: Invalid prop: type check failed for prop "extended". Expected Boolean, got String with value "true".

found in

---> <ArtistActions> at src/components/ArtistActions.vue
       <Artist> at src/views/artists/Artist.vue
         <VMain>
           <App> at src/views/App.vue
             <VApp>
               <Main> at src/Main.vue
                 <Root>

Also, this is for a separate issue/PR, but we need better content if there are no plays for the selected period. I selected an artist I know I listen a lot to, but haven't listened to in the past week, and thought this was broken until I figured out I had to change the period.

Fixed this warning (and create an issue to track the "empty" state of the stats page
