network: Keep key focus in dialog when removing networks

When the actor that has the key focus is destroyed, Clutter moves
the focus to the stage. In case the destroyed actor was inside a
ModalDialog, this breaks any keyboard interaction: keynav is broken
because the stage isn't in any focus chain, and access keys like
Escape because they are handled on the dialog's parent.

The only dialog that may destroy a child without recreating the dialog
buttons (and thus moving the key focus there) is the WirelessDialog,
fix it by keeping the key focus within the dialog when removing networks
from the list.
