* Remove the setting "lock on join" and related settings
* Hard-code the lockSettingsLockOnJoin=true parameter on create when any of the lock settings is used.
* The lock settings from the instance were not sent to the BBB API
* The global settings related to lock settings did not show
* lockSettingLockOnJoinConfigurable is not working so removed for now
* Fixed lockSettingsLockOnJoin setting
* As 'Send content change notification' is standard in all activities in Moodle 4.0
we should be removing 'Notify this change to users enrolled'
* Fix and adjust tests
