Fix for setting of the layer name

[juristr]

This piece of code doesn't work any more in the latest version:

olData.getMap().then(function(map) {
    var layers = map.getLayers();
    layers.forEach(function(layer) {
        if (layer.get('name') === 'japan') {
            var extent = layer.getSource().getExtent();
            map.getView().fitExtent(extent, map.getSize());
        }
    })
});

The problem is that the layer name is no more set correctly as already mentioned in issue #92. This PR fixes it.

Btw, one should add tests to make sure this doesn't happen again. I'd also be willing to add them, but the current tests on master don't pass and it would take me too long to figure out why.

Uff you're right there was one tests not passing and all the PR are inconsistent. Commented the invalid tests.

Thanks for your PR, good work, I'm merging it.

@tombatossals Hi, thx for merging in. Could you also release these latest bugfixes on bower as a v0.0.5? That'd be great, thx!

[tombatossals]

Of course, it's done.
