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.

I can't add rspec testing for this until https://github.com/rodjek/rspec-puppet/pull/106
is merged.
