Don't release 2.1.0 without fixing the sync loop

[jonathanstegall]

Describe the bug
Probably related to #420 and/or #444, but the functionality to prevent an infinite loop appears to be broken, at least in some cases. Need to identify when it's broken and why. In any case, can't release 2.1.0 while this happens.

To Reproduce
Steps to reproduce the behavior:

1. create a fieldmap, ex between users and contacts. Use these triggers:

2. create a new user that creates a new contact. 3. it seems like it never stops updating.

Expected behavior
It should stop updating

This was a Salesforce problem, not a plugin problem.
