check-ref-format --print: Normalize refnames that start with slashes
When asked if "refs///heads/master" is valid, check-ref-format says "Yes, it is well formed", and when asked to print canonical form, it shows "refs/heads/master". This is so that it can be tucked after "$GIT_DIR/" to form a valid pathname for a loose ref, and we normalize a pathname like "$GIT_DIR/refs///heads/master" to de-dup the slashes in it. Similarly, when asked if "/refs/heads/master" is valid, check-ref-format says "Yes, it is Ok", but the leading slash is not removed when printing, leading to "$GIT_DIR//refs/heads/master". Fix it to make sure such leading slashes are removed. Add tests that such refnames are accepted and normalized correctly.
