Remove cast to DBResourceManager

Remove cast to DBResourceManager

Remove cast to DBResourceManager, which no longer works after
DbLibService is advertised via Aries Blueprint and which is no
longer needed after DbLibService interface exposes getConnection()
method.
Updated version number - seems like an older 0.1.1-SNAPSHOT without
DbLibService change is being used, so trying to see if bumping version will
help.
