Cannot execute setup:db on a clean installation about lxhive

related to #111

@jcmedeiros , this should be fixed with pr 133.
Please run composer update (or remove the vendor folder and run composer install) and try again

I just tried a clean install on Linux Mint.

$ ./X setup:db

This suggestions didn't work immediately. However, after cloning the repository once again I was able to correctly set up the database.
Thanks!
