[229] Fix issue with --version option

[borland667]

What?

• When trying to access the root variable and and exception happened, root cannot be accessed because it does not exist.
• We have to use else there so we only try to access root when there is no exception happening.
• New get_project_root_or_current_dir_path method to get the root of the project path.

Why?

• To avoid issues when running leverage --version. Otherwise the command would just exit with an unhandled exception like it is described in the issue.

References

• Use closes #229

Sorry I'm a bit out of this right now...
But I have a question... why we are returning the pwd if no project root is found?
I mean, binbash Leverage is intended to be used inside a Leverage project context.... isn't it ok returning an error if no root is detected?
