[Bug 45023] TestBot Object Relational Mapper issues

Yet another issue.

15. New items must be saved through the collection

It's possible to call an item's Save() method to save it to the database after
modifying it. So the following code works:

my $Job = CreateJobs()->GetItem(1234);
  $Job->Status("queued");
  ...
  $Job->Save();

But it's not possible to do the same thing on a new item. So the following does
not work:

my $Job = CreateJobs()->Add();
  $Job->Status("queued");
  ...
  $Job->Save();

Instead one must do:

my $Jobs = CreateJobs();
  my $Job = $Jobs->Add();
  $Job->Status("queued");
  ...
  $Jobs->Save(); # Save **every new and modified item** in the collection
