Error when marking networks as modified

[Francisco Javier Díez]

When a network is opened, it is marked as modified. We can be seen by observing the “Save the current network” icon is active. It should be inactive.

If we save the network, the icon becomes inactive, which is correct. However, if we use the “Save as…” option, the icon remains active, which is incorrect.
