I missed all the entry pages when converting from set_abc() and get_abc() to set('abc', ) and get('abc').
Also fixed a wrong namespace for core_competency\external\performance_helper
Split it into a core exporter, and an extended one that adds information about the plan.
Also
* Remove userid from grade_competency_in_plan function (redundant)
* Improve the signature of list_evidence so it can handle completed plans (later)
* Rename read_user_competency_summary to data_for_user_competency_summary_in_plan
* Handle completed plans (list user_competency_plan as well as user_competency)
* Remove user_can_see_details_cap handling - if you can see the users plan you can see the user
* Pass final scaleconfiguration in the competency_summary_exporter
* Add docs comments to new templates
