The `default_actions` setting is not applied to the creator ACL when a new series is created.

[snoesberger]

Preconditions:

• custom actions are configured
• in the config file /etc/opencast/listproviders/acl.default.create.properties the default_actions parameter is configured, e.g. like this:

  # Default actions for every new role
  # Default: No actions
  default_actions=annotate,annotate-admin
  

Problem:
When I create a new series, the default actions are not automatically assigned to the series's creator ACL. However, if I manually add an additional user or role, the default actions are assigned correctly.
