Summary: Previously, when treemanifest would create packs of trees during pull, we allowed trees to be delta'd against trees in other packs. This resulted in smaller packs, but if the other pack disappeared for some reason (since it's a cache), the chain broke. This patch ensures that the first version of every tree added to a pack is a full text. This temporarily makes repacks worse, since the repacker doesn't know about history to produce deltas when combining packs. The next patch adds history awareness which improves the repack deltafication. Test Plan: Updated the tests, and inspected the new test results to ensure that all packs only had deltas within the pack.
