Labels for disk and network configuration buttons change on selecition of a node

[Roman Prykhodchenko]

Detailed bug description:
 On the Nodes tab there are two buttons for configuring disk layout and interfaces on a node. When zero nodes are selected with check-boxes the labels on those buttons display Configure Disks and Configure Interfaces. However, if at least one node is selected, those labels change text to Disk Configuration and Interface Configuration.
Steps to reproduce:
 1. Create a cluster
 2. Go to its network tab
 3. Add several nodes
 4. Select several nodes with check-boxes
 5. Clear all check-boxes all nodes
Expected results:
 The text on the above mentioned buttons does not change after [4] and after [5].
Actual result:
 The text on the above mentioned buttons changes after [4] and after [5].
Reproducibility:
 100%
Workaround:
 Not found
Impact:
 Users get mad
Description of the environment:
