9.0 Neos service routes not working

[mhsdesign]

Code like uriPattern: 'workspaces/{workspace.__identity}' cant imo work anymore due workspaces not being a doctrine entity.

neos-development-collection/Neos.Neos/Configuration/Routes.Service.yaml

Lines 137 to 149 in bc110df

	# Note: we need to specify the workspace as {workspace.__identity} in the uriPattern because if we just used
	# {workspace}, the properties could not be overridden through the parameters in the PUT request's body.
	# This is a shortcoming of the DispatchComponent and should be solved in a future version of Flow.
