Remove jest test callbacks from specs (1/3)

Vitaly Slobodinrequested to merge
vs/remove-jest-test-callback-part-two into master

Jest 27 does not support the test callback anymore so the following code is no longer valid:

it('test', (done) => { /* code */ })

This merge request is a part of our upgrade process to Jest 27 - &7002 (closed)
