Automated test failure of ledgerTable

Describe the issue you encountered:

https://travis-ci.org/brave/browser-laptop/jobs/213319341#L1988

  1) LedgerTable component only non pinned tabs:
     Invariant Violation: addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's `render` method, or you have multiple copies of React loaded (details: https://fb.me/react-refs-must-have-owner).
