repository: drop `initialize_the_repository()`
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()`.
