(core) Checks that an ACL formula can be parsed, and prevent saving unparsable ACL rules.

Summary:
- Fix error-handling in bundleActions(), and wait for the full bundle to complete.
  (The omissions here were making it impossibly to react to errors from inside bundleActions())
- Catch problematic rules early enough to undo them, by trying out ruleCollection.update()
  on updated rules before the updates are applied.
- Added checkAclFormula() call to DocComm that checks parsing and compiling
  formula, and reports errors.
- In UI, prevent saving if any aclFormulas are invalid, or while waiting for the to get checked.

- Also fixed some lint errors

Test Plan: Added a test case of error reporting in ACL formulas.
