The withNeeds function was calling getSelectedReleases with false, false
for includeNeeds and includeTransitiveNeeds, which caused it to ignore
the --include-needs and --include-transitive-needs flags.
This fix:
1. Computes includeNeeds before calling getSelectedReleases
2. Passes the correct flags to getSelectedReleases
3. Sets st.Releases to selectedAndNeededReleases instead of deduplicated
4. Passes IncludeNeeds=false and IncludeTransitiveNeeds=false to PlanReleases
since the needs are already included in selectedReleases
