Description Erik Damrose

If no server or connection is present when opening the UVMM UMC module (i.e.: the tree is empty), there is an endless reload loop between the tree and the grid.

Symptom: Alternating umcp requests umcp/command/uvmm/query and umcp/command/uvmm/groups/query

This causes high load on the client browser while displaying the module, and makes it hard to actually hit the 'create' button to setup a new cloud connection. This is a regression introduced by a recent errata update.
