Before this change, --conflict-loser pathname assumed --conflict-resolve none,
following the legacy behavior prior to v1.66. This produced unexpected behavior
when used with a different --conflict-resolve option.
This change fixes the issue by ensuring that --conflict-loser pathname looks for
the correct name on the side not being renamed, when only one side should be
renamed.
