Angular: Footer cannot be translated in 8.0.0+

[OmarHawk]

Overview of the issue

Language switch of footer doesn't work (it will always show the plain text). Import was forgotten, when migrating to standalone component.

Motivation for or Use Case

Everything should be translateable in the default UI.

Reproduce the error

1. generate Application with at least two languages.
2. start up
3. try to switch language
4. footer is not translated (but all the rest)
