t/helper: stop re-initialization of the_repository

While "common-main.c" already initializes `the_repository` for us, we do
so a second time in the "read-cache" test helper. This causes a memory
leak because the old repository's contents isn't released.

Stop calling `initialize_repository()` to plug this leak.
