Bug 15339: TestBuilder warnings (tests)

Makes TestBuilder::build() alert the user when unreognized parameters
are passed, which happens when the user supplies the column values
directly, forgetting the 'value' hash.

This patch contains the tests that doubles as a demonstration
of the kind of error the patch is intended to prevent.
