@aorumbayev It appears that we only have approval tests checking token refresh when invoking login. Should we be checking token refresh via fund, refund and limit?

[aorumbayev]

@neilcampbell added explicit batch of unit tests to test the behavior of refreshing the token instead of duplicating it in other methods, plus some minor refinements in the fixtures

[aorumbayev]

@neilcampbell @robdmoore ready for re-review. Latest tests rely on latest custom error responses from dispenser api
