t3302-notes-index-expensive: Speed up create_repo()
Creating repos with 10/100/1000/10000 commits and notes takes a lot of time. However, using git-fast-import to do the job is a lot more efficient than using plumbing commands to do the same. This patch decreases the overall run-time of this test on my machine from ~3 to ~1 minutes.
