Fix a performance regression in obligation deduplication.
Commit 8378487 from #114611 changed the location of an obligation deduplication step in `opt_normalize_projection_type`. This meant that deduplication stopped happening on one path where it was still necessary, causing a couple of drastic performance regressions. This commit moves the deduplication back to the old location. The good news is that #114611 had four commits and 8378487 was of minimal importance, so the perf benefits from that PR remain. Fixes #116780, #116797. (cherry picked from commit 91f2fbc867bfc31f2e103b09e605c61f1a450b33)
