Subject: [PATCH] Fixes active index usage for radial LGR grids

Ensures that active cell indexing is always used for temporary local grid refinements (LGRs) of radial multi-grids.

The  TestCase_Completions_Export loads a grid with several LGRs. This test case failed due to the changes for radial grids.
