[FEATURE] Option to exclude display of untranslated content
[TASK] Rename internal method to reflect output type correctly
[BUGFIX] AbstractContentVH returned content record AND the translation

This change fixes an issue where the method getContentRecords would return
the original and the translated content record if the language of the
original was set to all and a translation for the current language was
provided.

Fixed by selecting only content records with no visible translation for
the current language.
[TASK] Refactor variable name from hideUnTranslated to hideUntranslated
