Subject: Workbench: Ensure `output` attr is initialised when creating
 workbench

Since all `Workbench`es must have an associated `ReferentialSuite` via
`output`, if none is provided when creating a new `Workbench`, create
one automatically.

This is done in a `before_validation` callback (eck, AR callbacks).

In order for our prior 'should validate_presence_of' test to continue to
work, we have to work around the new callback, otherwise Shoulda can't
set `output` to `nil` to run its expectation and the test fails.
