feat(resource): create link / collection resource (DSP-1835)

[kilchenmann]

resolves DSP-1835 and resolves the issues mentioned in DSP-1820

After creating a linkObj resource it opens the new resource in a new tab. In this PR I have integrated the same logic when creating a new resource instance.

There's an "ugly" error from Angular lifecycle hook where I wasn't able to resolve it resp. when resolving it in DSP-APP we got another lifecycle hook error from DSP-UI and nothing works anymore. I hope to resolve the issue when moving DSP-UI components to DSP-APP (DSP-1857):

ERROR Error: NG0100: ExpressionChangedAfterItHasBeenCheckedError:
