[translation] Converting version for branch names
[translation] Converting version for branch names

Since Zanata does not support '/' characters
in project version names, i18n uses '-' instead of '/'
for branch names.

By replacing '-' with '/', translation statistics
will cover not only master branch, but also other branches
such as stable/mitaka and stable/liberty.
