test plan:
- enable the "default due time" feature
- the account setting for "default due time" should
appear on the account settings page
- it should feature a dropdown where the top element
is the default (initially 11:59pm) and other
options for each hour of the day
- if you set it in an account and save, then go to
the settings page of a subaccount or course,
you should see the setting applied
- it is in the top slot of the dropdown since it
is the inherited setting
- in a subaccount or course, you can choose to
override the inherited setting
- if you change the subaccount/course setting back
to the account setting, then go up the tree and
change the parent account's setting, the
lower context should follow
