QField Canvas location lock improvement.

PR Description:

At present, when the canvas location is locked and the user zooms in or out with a mouse, the lock will break.

Fix:

Using same approach in zoomInButton and zoomOutButton:

if (gnssButton.followActive)
        gnssButton.followActiveSkipExtentChanged = true;

Demo:

Now zooming in/out wont break lock.

@mohsenD98 , we need to change this a bit so we don't introduce a "random" item id within MapCanvas.qml (makes it a lot harder to test individual components).

I'd go for adding a signal aboutToZoom(), and then add the logic in qgismobileapp.qml (where gnssButton lives) by listening for that signal.

Good point :+1:
