Two tests in network::fetchlocal explicitly set a cleanup function to free and remove the created sandbox repositories. This is not necessary, though, as the cleanup function executed after each test already takes care of cleaning up after them. Remove the code to avoid needless code duplication.
Upon downloading the pack file, the local transport will iterate through every reference using `git_reference_foreach`. The function is a bit tricky though in that it requires the passed callback to free the references, which does not currently happen. Fix the memory leak by freeing all passed references in the callback.
References passed to the callback function of `git_reference_foreach` are expected to be owned by the callback. As such, they are never being freed by `git_reference_foreach`, but will have to be freed by the caller. This small detail is never mentioned in the function's documentation, though, making it easy to get wrong. Document this to make it discoverable.
The test refs::iterator::foreach_name iterates through every reference and copies its name into a local vector. While the test makes sure to free the vector afterwards, the copied reference names are not being free'd. Fix that.
