Make Collection::save() play well with existing collections & non-null
columns

Bug 1381811: Collection::save() would create a new (empty) collection by
passing 0 as the id to the Collection constructor, even if the supplied
$data included an "id" field. Since the id was not supplied to the
constructor, it does not pull the collection's current data from the
database.

It would then call Collection->commit(), which would notice the "id"
field and do an update instead of an insert into the database. But due to
the way the Collection class is written, it would try to populate every
field of the collection table, rather than just those supplied in $data.

This means that all the database fields not supplied in $data, would
attempt to be filled with NULL. This threw an error because of the new
collection.submittedstatus NOT-NULL column.

Bug description:
  Mahara 1.10rc1

  Editing a collection's title or description produces an error.

  1. Create a collection
  2. Save it
  3. Click the "Edit title and description" link for that collection
  4. Click "save"

  Copying of a collection produces the same error. Tested in Portfolio
  and groups.

  1. Create a collection.
  2. Copy the collection. Error (see below shows up). Collection is created though.
