Do not reload if not initialized

I've had the scenario come up a couple times where my data model is updated before ng-table is "ready". This prevents something from triggering reload and having a javascript error.

I'm having this very same problem too, also if you look at Example #14 you will find a piece of code like this:
$scope: { $data: {} }
attached to the ngTableParams object, I think that it's there to mitigate some of these errors, but it can lead to other internal side effects, because you are not completely mocking the scope object (it's missing the $emit function, which is used elsewhere in ngTable source).
