Revert "Temporary commit to debug test failure on Travis"

This reverts commit 4e3f3f3b5810409960b3690e83a073e2a965881e.
Set creation of policy fixtures to a day ago

Travis runs tests slower than on my machine so policies were
"edited 1 minute ago" on Travis but "edited less than a minute ago"
on my machine. This fixes that by just setting it to a day ago.
