Block template - missed check for support

[madeinua]

I suppose this part is missed at the beginning of locate_block_template():

if ( ! current_theme_supports( 'block-templates' ) ) {
    return $template;
}

Hi @kapilpaul, thanks for the patch!

The tests on ​PR 2246 are failing because block-templates support is not added until the setup_theme action has run. I've commented on the PR to request a change that will fix the tests so that this fix can be considered for commit.
