nitpicker: fix gcc build error

Browse Source 
An early version of nitpicker used a pointer as 'owner' with the null
pointer representing nitpicker's built-in views, which are nowadays
represented by 'Main::_global_view_ower'. The null-pointer check is a
left-over from the earlier days.

Fixes #4847
