Make testing use strict variables
Fix for strict_variables = true.

00:17 < kwa> tdoran: what if we just said 'screw it' and made it default to true
00:07 < josnyder> tdoran: no, that's not what I meant.  I meant change to '= true', but kwa's point is valid
Fix the tests in travis
Add the site.pp fixture
Better error if we have no teams data
Default to empty
