PLAT-1524: Add on_delete kwarg to ForeignKey & OneToOneFields

Update copy for password compliance message to be more clear.

Fix PDF cert gereration/regeneration and URLs.

Django 2.0 will make this field required for `ForeignKey` and `OneToOneFields`.
In previous versions the option defaulted to `models.CASCADE` when not
specified. This change should make the deprecation warnings in the current
Django version go away.

The migrations where also modified, but the changes should not cause a change in
the database schema since `models.CASCADE` was already the old default.

Allow scrolling after insert/edit image in Studio

The scroll lock class `modal-open` is removed from the body when the
EditImageModal is closed using the "Close" or "X" button, but not when the
"Insert Image" button is clicked. The submit button handler now calls the
`closeImageModal` handler too so that the `modal-open` class is removed after
inserting or editing an image.
