Wrong template for YouTube content element stored in database

[fritzmg]

The SQL dump erroneously uses the ce_player_responsive template here for a content element that is actually a YouTube video (which would use ce_youtube template otherwise). Thus the following error will occur:

TypeError:
implode(): Argument #1 ($pieces) must be of type array, string given

  at vendor/contao/core-bundle/src/Resources/contao/templates/elements/ce_player.html5:13
  at implode(' ', null)

  at Contao\ContentElement->generate()
     (vendor/contao/core-bundle/src/Resources/contao/elements/ContentYouTube.php:50)
  at Contao\ContentYouTube->generate()

To fix this the customTpl field should be set to an empty string in the SQL dump for this content element.

Confirmed.
