#20562: Minor fix for ordering

A very small fix for the case where the root password has been changed by hand and then you change your mysql::server entry to match.  If you also change any mysql::db entries at the same time this causes those to be attempted before your /root/.my.cnf is updated.

NOTE:

I can't add rspec testing for this until https://github.com/rodjek/rspec-puppet/pull/106 is merged.  I would prefer not to merge this until we add those ordering tests, but I wanted to at least get a PR up for the person with the issue.
