Description Zac Medico gentoo-dev

When VdbMetadataDelta.applyDelta() processes an "add" event, another package instance from the same slot (that was replaced) can remain in the cache. Then IndexedVardb.match returns both instances, and search.getInstallationStatus() can randomly show the wrong instance installed.

The "add" event handling was fixed by 89a48c206f007d4b1e323c089842cd6475c1eea2, but "remove" events need similar handling. There's a new patch in my branch:
