Fix soft delete returning test.

[Mitika-d]

Fix TestSoftDeleteReturning test by adding quoted identifiers and redirecting soft-delete to customised update clause with bulk returning instead of default update and returning clause. QueryContext is removed for soft delete as it is not compatible with update clause.
