  - xci: get-opnfv-scenario-requirements: Fix local scenario sync

    Commit 07747a53901e550280afb421b6fcbebc8994e93a ("xci: playbooks: Fix
    synchronization of external scenarios") fixed copying of external
    scenarios but broke internal ones because the regexp was wrong. The
    variable was not evaluated properly so nothing was replaced for internal
    scenarios. This also fixes a problem when the scenario and the role
    names differ so we make sure that the role with the correct name is
    created.
