CRITICAL: when mounting the same directory twice the source directory get's deleted

[HeikoBoettger]

When I the same container with the same source directory using this plugin twice, the source directory on the host is removed.

There is forked version of this plugin (https://github.com/StudioEtrange/docker-volume-bindfs.) which doesn't seem to have this problem.

The error message looks the same as reported in #4.

Yes I think it is the problem with the volume list not correctly managed.
This version should solved this https://github.com/StudioEtrange/docker-volume-bindfs
