Can't change root password to blank

[joshbetz]

After setting the root password to a non-blank value, I want to change it back to blank. I can change the password to another non-blank value, but I can't change it to ''.

I'd consider it somehow an edge case, but thanks for the notice.
Will tackle it when I find time...

I'll try to look into it too. I though it was https://github.com/example42/puppet-mysql/blob/master/manifests/init.pp#L354, but change that didn't seem to fix it.
