Fix wrapping redundant cities in the economics view

We were resizing columns to avoid wrapping with resizeColumnsToContents,
then resizing rows. This produced horizontal scrolling and strange
behaviour when the redundant list got long.

Fix this by:
1) Setting the last column (redundant cities) to use all remaining
   space, and
2) Adjusting the width of all columns except the last.

Closes #2289.
