python: fix scope assignment for indirect parameter sets (#11277)

Previously, when assigning a scope for a fully-indirect parameter set,
when there are multiple fixturedefs for a param (i.e. same-name fixture
chain), the highest scope was used, but it should be the lowest scope,
since that's the effective scope of the fixture.
