With commit [1] and its parent ones of the same PR, some OWL Component became LegacyComponent, and some were adapted to work without the previous Component compatibility methods. The theme selection component was forgotten. Steps to reproduce: - Install website with themes repo - Go through the configurator flow and select a theme - A traceback appears and you cannot complete the flow This commit loads the rpc service in the ThemeSelectionScreen component.
