New EXPLAIN feature breaks db debug when no 'db' component setup

[joe-meyer]

My scenario is such that my application uses 3 different database components, however I do not call any of these database components 'db'. When I click to go to the db panel of the debug module, I am presented with Unknown component ID: db

I also haven't tested it but I'm not sure how the new explain feature would work if you did have multiple databases and queried multiple databases. It seems like you could only have explains for a single database or you would have to somehow create multiple panels for each and it wouldn't make any sense to try and run an explain for a query from "DatabaseA" on "DatabaseB" or vice versa. Perhaps i'm overlooking something here though?

I set the following in my config and it ended up yeilding 2 database panels, but the same queries were listed on both. My database doesn't support explain so I wasn't able to test how that reacted when I did this but I imagine it probably would cause issues since i'm not sure how it knows which queries belong to which database.

    $config['modules']['debug']['panels'] = [
         [
            'class' => 'yii\debug\panels\DbPanel',
            'db' => 'mfg'
        ],
        [
            'class' => 'yii\debug\panels\DbPanel',
            'db' => 'ftdb'
        ]
    ];
