bug: source:check with same names in two datacentres get same check data

[roobert]

If I have two datacentres and an instance of Uchiwa connected to both and I create a check with a modified source, e.g: 'source: os_security_checks, name: apt_security_updates' then although the clients are both listed in Uchiwa, the check data updates for both checks at the same time with the same value for both checks, even though individually the check data should be different.
