Updated git fork berhavior to decide whether to clone or not
* when --clone is not given, lookup whether --path (and <--path>/<repo_slug> is a git repo ; - if it is, adds the fork to that repo - if it is not, then consider --clone has been setup * when --clone has been given, create a new repo at <--path>/<repo_slug> if it does not exists. * updated tests * fixed delete test * fixed request_fork test Signed-off-by: Guyzmo <[email protected]>
