Don't reset the local repo
Instead of "resetting" the local repo (git remote update, git checkout master, git reset --hard, git clean -xfdq) before merging each change, just fetch the remote ref for the branch and check that out (as a detached head). Or, if we are merging a change that depends on another change in the queue, just check that change out. Change-Id: I0a9b839a0c75c04eca7393d7bb58cf89448b6494
