Atlas popup should not show fields that are NULL

[gioman]

What is the bug?

Following the ticket/discussion where it was explained why it was chosen to not show NULL attributes il LMWC popup, then is unclear why the Atlas popup will show them. For the sake of consistency both should behave the same.
