Syncing breaks if more than ~ 30 labels exist in a repo

[pjatx]

Steps to repro:

1. Create a blank repo
2. Load in 20 labels
3. Sync to another repo
4. Add 15 more labels
5. Sync again to same repo

Expected

• 35 labels exist in destination repository

Actual:

• Script attempts to remove ~ some labels instead of syncing all

Not sure on the exact ceiling of the number of labels or if that's the problem, but can reproduce this behavior now and I am trying to sync about 33 labels to 8-9 other repos.

It somehow is missing some of the labels when determining what needs to be added and deleted so some are added correctly, but others are removed incorrectly.
