There is an old pre-existing memory leak in repo_init() due to failing to call clear_repository_format() in the error case.

It went undetected because a specific bug is required to trigger it: enable a v1 extension in a repository with format v0. Obviously this can only happen in a development environment, so it does not trigger in normal usage, however the memleak is real and needs fixing.

Fix it by also calling clear_repository_format() in the error case.
