failed to create initial commit: failed to create initial commit: exit status 128

If the user has not configurated their name and email, the initialization of a git-flow workflow is incomplete (but considered as complete).

To reproduce

Do not set (otherwise unset) your global and local user configs (as user.name and user.email)

> git flow init  --preset gitlab # for example
Error: failed to create branches: failed to create base branch 'production': failed to create initial commit: failed to create initial commit: exit status 128

> git flow init  --preset gitlab # to test a second time and observe git-flow considered it complete
Error: git-flow is already initialized in this repository. Use --force to reconfigure

> git flow overview
# Will see considered as complete

> git branch -l 
# no branch production

Expectation

1. git-flow should check the completion of the initialization before considering it works
2. git-flow should check the user name and email is configurated before doing anything

git-flow-next should also be able to create a git repository if it does not exist (to avoid people do before git init with branch name that will not respect the workflow they will initialize just after):

Current behaviour:

> git init --initial-branch master
> git flow init --preset gitlab
> git branch -l
* main # 'master' branch has been changed to 'main'
  production
  staging
