Fix (unreported) liboverride resync creating garbage data in some cases.
Regression caused by the introduction of partial resync in February 2022
(rB1695d38989fd482d3c). Code was missing adding some existing overrides
to the mapping in some specific cases, causing resync to create 'new'
ones instead of re-using existing ones.
This commit also adds a basic resync testcase that illustrates this
issue.
