During a 'git push' command, we run 'git send-pack' inside of our transport helper. This creates a 'git pack-objects' process and passes a list of object ids. If this list is large, then the pack-objects process can spend a lot of time checking the possible refs these strings could represent.

Remove this extra check by setting core.warnAmbiguousRefs to false as we call 'git pack-objects'.
