Notification fix

edit.php
1.	In the instance setting, users who should receive the application notification would not save.
a.	Solution: Save the users to table enrol->customtext3.
edit-form.php
1.	In the instance setting, users who selected to receive the application notification would not set as selected (may confusing people).
a.	Solution: Query to table ‘enrol’ and the selected users as selected.
lib.php
1.	After make change to instance settings, users with ‘enrol/apply:manageapplications’ capability would not receive enrollment application notification.
a.	Sender and receiver share the same variable ($user) in send_application_notification()
b.	The sender in send_application_notification() is set to $contact, which assigned to user with ‘enrol/apply:manageapplications’.
2.	Variable $value in get_notifycoursebased_users() is assigned to $instance->customtext2, while customtext2 is the Custom Label. Therefore, this function would not return the user should receive application notification.
a.	Solution: change customtext2 to custometext3.
3.	Admin will receive two notification from one application.
a.	get_users_from_config() in get_notifyglobal_users() without a ‘false’ in third parameter.
b.	Solution: add ‘false’ to third parameter.

Environment: Moodle v3.6.2+ (build )
