Now that we have dropped `the_index`, `initialize_the_repository()` doesn't really do a lot anymore except for setting up the pointer for `the_repository` and then calling `initialize_repository()`. The former can be replaced by statically initializing the pointer though, which basically makes this function moot. Convert callers to instead call `initialize_repository(the_repository)` and drop `initialize_thee_repository()`.
