use params.get instead of lodash get

[BeritJanssen]

Close #1297.

[JeltevanBoheemen]

Good to see this fixes it. Any idea why? :)

[BeritJanssen]

Yes: params is not a simple object, but a Params object, which has a method .get. Otherwise, we'd need to do _.get(params.params, ...), but since we already have a default for this.neighbours, this is not necessary.

Did you test this? This description sounds like ParamMap, not Params.

[BeritJanssen]

Yes, indeed, the object that gets passed in is a ParamMap (in ParamDirective: this.route.queryParamMap.subscribe...). I went ahead and corrected the typing.
