Mock providers not cached

[OliverJAsh]

var di = require('di');

function Bar() {}

di.annotate(Foo, new di.Inject(Bar));
function Foo() {}

di.annotate(BarMock, new di.Provide(Bar));
function BarMock() {
    console.log('initialise BarMock');
}

var injector = new di.Injector([BarMock]);

injector.get(Foo);
injector.get(BarMock);

I expect that BarMock should only be initialised once, as the second time I call injector.getPromise, BarMock has already been initialised – the subsequent request should fetch the cached version.

I am seeing:

$ node test
initialise BarMock
initialise BarMock

I expect:

$ node test
initialise BarMock

@vojtajina Really keen to fix this. Any pointers?
