Leader cannot start with large number of tokens

[sakridge]

If I run setup.sh -> leader.sh with tokens=2000000000, I see this exception when the leader tries to start:

I experience this with the default number of tokens (1_000_000_000)

[mvines]

Oh! I see this too

Either transaction-less entries aren't getting registered or they're getting purged from the last_ids dequeue too early.

two workarounds

1. backout: eec19c6, 5e91d31 & 3dbbb39
2. use less tokens (100,000)
