Bring back the admin label on the block

Moving back to needs work as on subsequent edits of the block, it tries to reset the admin label back to the views default.

You needed to get the label from configuration when set. Adjusted the MR.

This change makes sense, looks good to me.

The label field is required, so after the patch, editing existing block instances forces to provide now a title. I think that it could be optional, since create new instances without a label is a admitted situation.

In addition to that, there is another "Title" field when the "Override title" options is enabled, which might cause confusion. Renaming the instance label as "Administrative title" could be a work around for that.

Aren't both of those scenarios valid? I see in other block instances the title is required and those that have override title the field that displays is title.

But if it's a blocker can we just add $form['label']['#title'] = $this->t('Admin label'); to the bottom of the change?

But MR solves the issue I was seeing. I'm currently using 2 blocks to have the sort filters in the top right and all others in the left column.
