tests: conditionalize extension tests for extra extensions

tests: conditionalize extension tests for extra extensions

If extra extensions are loaded (e.g. via --extra-config-opt),
the tests conditionalized in this commit fail in ways that
are dependent on the extensions that are loaded. So let's
skip them when that scenario is present.

This drops the number of failures for the simplestorerepo.py
extension to 4.
