Bug 4907: make 'Organize by' filter in suggestions reflect selected option

When using the 'Organize by' option to change the display of the
suggestions, the option is applied, but the pull down always jumps
back to the first entry 'Status'.

This patch fixes that.

To test:
- Try out all settings and verify that after the page reloads the selected
  option is applied to your suggestions and the pull down shows
  the option you selected.

Note: Until bug 10519 is properly fixed the tabs will not show
the correct descriptions, but the URL will show you the selected
option as parameter: displayby=acceptedby
