Set appropriate branch key in _horizon_translations_pull

Once branch is defined in _horizon_translations_pull, variable
horizon_translations_project_version was not influencing anyhow on the
pull process, as it was set as default variable, when branch not defined

With this change horizon_translations_project_version was set as
branch in vars, with default value of master.
