Bug: Outbound Dependencies should be refreshed after version rollback

wizard:

In Outbound dependencies:

[ashklianko]

That was fixed in #456; In this task I am fixing issue for a Outbound Dependencies section shown when content has no any dependencies: say you insert url into browser like admin/tool/com.enonic.xp.app.contentstudio/main#/outbound/1759b321-a367-44cc-96bd-b4bdbb6f9a97

But content with id from url might not have any dependencies already; In this case you'll see Dependencies Section open and spinner running in content grid;

Fixed by checking content's dependencies before routing to content studio inbound/outbound url;
