Fixes #844 #5725 - correct hosts count in puppetclass

The timestamp of this migration ```20140922084848``` is < than the timestamp of the other migration ```20141109131448```. This means the user won't be able to run db:migrate because it'll try to trigger the ```fix_hosts_counts``` task without having the ```total_hosts``` column. Change this timestamp to something like ```20141109131450``` and that'd be fixed. (that's what I did to test the PR)
