Key	Value	Comments
PHP version:	7.2.19
Contao version:	4.9.8
MetaModels version:	dev-feature/2.2.0
Installed MetaModels packages:	attribute_alias, attribute_checkbox, attributeselectattribute,tags, attribute_text, attributetranslatedaliasattribute, translatedlongtext, attribute_translatedtext, translatedurl,(attribute_url), filter_checkbox, filter_fromto, filter_perimeter, search, filter_range, filter_register, filter_select, filter_tags, filter_text	missing attribute_url causes the application to break

Issue description

(Describe the problem you are having)

Steps to reproduce

[First Step] Install core and attributes including attribute_translatedurl but except for attribute_url, update db etc.
[Second Step] In the Contao backend, click on MetaModels > Attributes
[Error] See error message below
[Remedy] Installation of attribute_url solves the issue

Describe the behaviour of the application
