[Sushil Kumar]

trove/tests/util/users.py contains ServiceUser.__str__ which is assigning values after a return statement.
This assignment has no use.

Also it assigns the values which are not available in the method.

    Cleans up ServiceUser.__str__ method

    Reasons:
    - ServiceUser.__str__ in trove/tests/util/users.py contains code
      after the return statement.
    - This code after unconditional return statement has no use.
    - Thus, ServiceUser.__str__ method needs cleanup.

    Changes:
    - Removes the statements after return statement.
    - Adds tenant name to the __str__.
