Check the exact mount point whereas checking a parent dir allow
us to simplify the implementation of ``is_volume_used``. The new
implementation to be included in next version of compose is also
more solid (it doesn't rely on ``docker inspect`` that can stall
execution of the script if a container is stalled).

Indeed, when changing project name, ``rocketchat`` would create a new
database and would not be able to use previous database.
``mongo`` side is here to ensure proper update of existing installation
that would use previous naming scheme.
