Broken sorting of bonds on interfaces configuration screen

[Julia Aranovich]

Steps to reproduce:
1. add node with 8+ interfaces to environment
2. go to node interfaces configuration screen
3. create 3 bonds: bond0, bond1, bond2
4. create the 4th bond: bond3

Expected result: bonds are displayed in the order: bond0, bond1, bond2, bond3
Actual result: bond1, bond2, bond0, bond3 order

5. save changes and go back to Nodes tab
6. go to the node ifc configuration again

Expected result: bonds are displayed in the order: bond0, bond1, bond2, bond3
Actual result: bond3, bond1, bond2, bond0 order
