Arvados » Arvados Workbench 2

In workbench2 it is not possible to navigate to a collection using the PDH, only UUID is possible.

There are the following cases:

1. There is ONE collection with a given PDH
2. There are MANY collections with a given PDH
3. There are no collection with a given PDH

The following behaviour is expected.

1. When accessing a collection like this wb2.host.name/collection/c9805738ba048a0b108d438acd0c1eec+187 it should resolve to the UUID and open the collection
2. In this case the Workbench2 should provide a list of collections that exist and are accessible for this PDH and allow the user to select one which will be opened
3. The obvious will happen, nothing found.
