[FIX] web: prevent crash when exporting all data

In the list controller, some code to determine the active domain to
export was causing a crash.  It was easy to see: just select all records
in a list view, then click on 'Export' in the sidebar.

Note that the data_export code is still quite old, and did evolve
organically.  It does not conform to our new design principles, in
particular, the way component should communicate. But this is a task for
another day.
