[BUGFIX] Enable generic backend preview in workspaces

The TYPO3 backend offers a generic preview mechanism for any type
of record. The configuration includes being able to pass needed
parameters to some kind of plugin/controller.

The workspaces also offer a preview feature, but do not take the
backend preview configuration into account in the Workspaces
module.

See the Forge ticket for more explanations and test setup.
