    Remove extraenous instantiations of managers

    There were cases where a number of the API managers were being
    instantiated more than one time. This could cause a number of
    odd edge cases where the managers would have different
    configurations and/or different dependency injection results.

    The managers should now be properly instantiated only once
    unless explicitly required (e.g. testing the token provider
    manager raises an exception in badly configured states).
