Speed up tests by reducing the initialization work.
The initialize call performs a lot of operations, the majority of which

aren't needed for unit tests. By cutting off this work, we save a few

seconds in total across the test run. This doesn't appear to have any

negative impact on unit tests.

Ran the unit tests and saw a roughly 6-8 second decrease in time (after

disabling online tests, to keep run times more consistent). All tests

passed.
