Ubuntu Pro: Changing network state wreaks havoc

[Nathan Teodosio]

* Impact
Changing the connection state in Ubuntu Pro pages wreaks havoc in the program, often leading to segmentation faults.

This is caused by the pass of the wrong pointer to the network state change callback.

* Testcase

Use the testcase on bug #2003231 to validate the Ubuntu Pro workflow, while on the Ubuntu Pro page change the connectivity, the UI should adapt without crashing

* Regression Potential

The patch is a pointer change in the connectivity callback from the Ubuntu Pro page so if a bug was introduced it would be on that screen and having to do with connectivity changes

Thanks, uploaded to the review queue now. It's not needed in Lunar since that feature doesn't exist there

I met segmentation fault when doing Quit in gnome-initial-setup(42.0.1-1ubuntu2.1 and 42.0.1-1ubuntu2.2). Not sure if it's the same issue, I opened a new bug for it.

The segfault on quit is bug #2004518 and another upload is waiting in the queue for it

Testing 42.0.1-1ubuntu2.2 it correctly handles the connectivity change. Turning off the connection would lead to a blank page and stdout errors before but now it correctly display the warning label, no warning printed and the page doesn't blank. Marked as verified
