With latest version of Mercurial plugin (2.14), the Mercurial clone configuration is not correct.
The "paths.default" does not contains the Repo URL, but instead it contains the clone PATH on the file system followed by the Repo URL.
the problem appeared since version 2.14. After rollback to plugin 2.12, no issues.
because of this, we cannot run "hg push" command as the URL is incorrect in the local repo
