Potentially unavailable service requested in ModellerBase
Problem/Motivation
The ModellerBase class requires the service eca_ui.service.token_browser which may not be available, if the eca_ui module doesn't get installed.
Proposed resolution
This service requirement can be moved into the ModellerBpmnBade class which is hosted in the eca_modeller_bpmn sub.module that requires the eca_ui module and therefore won't have that issue.
