repository: fix free problem with repo_clear(the_repository)
the_repository is special. One of the special things about it is that
it does not allocate a new index_state object like submodules but
points to the global the_index variable instead. As a global variable,
the_index cannot be free()'d.
Add an exception for this in repo_clear(). In the future perhaps we
would be able to allocate the_repository's index on heap too. Then we
can revert this.
the_repository->index remains pointed to a clean the_index even after
repo_clear() so that it could still be used next time (e.g. in a crazy
use case where a dev switches repo in the same process).
