Remove obsoleted sectional_codeowners FF in tests
What does this MR do?
As part of work to iteratively build section codeowners I did development
work behind a feature flag (sectional_codeowners) which can be removed now
that sectional codeowner processing has aligned with the legacy processing
- feeding a sectional or legacy formatted file through either the legacy
or sectional processing routines will return the same data (the only
difference being that sectional data through the sectional parser will add
to the Entry object the section in which it was found.)
