Open connection-editor for Wi-Fi connection, edit the
Wi-Fi channel and leave the cursor inside the channel
input field. Then press ESC to close the window.

This lead to a crash:

Previously we only checked the existence of the proxy; we should
instead verify that MM is actually running.

Broadband devices stay uninitialized if they are added before the
ModemManager is running. Call again the device_added method after MM
becomes available.

Function nm_setting_duplicate() can't copy object's data.
As a result a value of the "Ignore CA certificate" checkbox was
always lost. So don't copy settings, just use g_object_ref() again
and remove the 8021x setting from the temporary object to prevent
the clearing of secrets.

When @tmp_connection is destroyed it clears all its secrets: remove
the 802.1x setting before unreferencing the connection since the
setting is used by another connection.

Previously, a failure to nm_vpn_editor_plugin_get_editor() was not considered fatal for the
VPN page, and thus it whould show a dialog without VPN tab. Load the editor early and fail.

Previously, when selecting the "Create" button with the keyboard (tab key),
pressing ENTER would still invoke the "Cancel" action.

We either want that ENTER invokes the "Create" action, or that ENTER
invokes the currently selected button (be it "Create" or "Cancel").

This patch changes the UI to do the latter.
