bug 2295 [followup 2/2]: initialize data in startup method

It was observed that the %thash and @formats variables
were not being properly initalized during a make single-test run.

To ensure initialization, created startup and shutdown
methods to initialize those values as part of the
test object.

I have not yet investigated why the original way of
setting up %thash and @formats did not work.
