Fix #61003
Fix #61003

Restored the previously shifted check for version_to_remove in
old[target]. This had been extracted along with the correctly extracted
double pkg_params[target] lookup, but that lost the `target in old`
guard.

Putting the check back here prevents KeyError when looking for a
non-existent target in `old`.
