Error in ContactList & GbList templates with ImageViewHelper

[Thomas Scholze]

Oops, an error occurred!
The argument "image" was registered with type "object", but is of type "integer" in 
view helper "TYPO3\CMS\Fluid\ViewHelpers\ImageViewHelper".

<f:image image="{contact.photo.uid}" alt="Porträt von {contact.name}" title="{contact.name -> f:format.stripTags()}" maxWidth="100" />

must be

<f:image image="{contact.photo}" alt="Porträt von {contact.name}" title="{contact.name -> f:format.stripTags()}" maxWidth="100" />
