Description of problem:
NM don't add custom routes from system-ethx config, custom created network connection work (add additional routes).


Version-Release number of selected component (if applicable):
System-config-network - 1.5.99
Networkmanager        - 0.7.996

How reproducible:
Always

Steps to Reproduce:
1. Config netwok interface through System-config-network as:
    adapter - ethX
    static ip - 10.10.5.2, mask 255.255.255.0, gw - 10.10.5.10, routes - 10.0.0.0/8,gw - 10.10.5.20; 192.168.0.0/16, gw - 10.10.5.20
   No ipv6
   with checked - use networkmanager at this connection
2. Configure Networkmanager to use this "System ethX" 
3. Run "route" out in console (see result 1)
4. Disable networkmanager usage for this connection in system-config-netwok
5. Run "route" out in console (see result 2)
6. Enable networkmanager usage for this connection in system-config-netwok
7. Create custom wired connection at network manager with data from step 1. )with metric 1 at additional routes)
8. Activate this connection in networkmanager.
9. Run "route" out in console (see result 3)
  
Actual results:

1. output at step 3

(don't look at metric column)

at all steps.

Additional info:
Only 1 eth adapter in system.
Updated to current state with fedora and fedora-update repository.
