fix: only filter by invocations_rank_index when no invocation_id is specified

When using 'edr report --select invocation_id:XXXX', the report showed 0
tests for non-latest invocations because the invocations_rank_index == 1
filter ran unconditionally after the invocation_id filter, removing all
results where the selected invocation wasn't the most recent one.

This mirrors the existing correct pattern in get_test_results_summary().
