Select all and delete button issues (upgrade/form-filter branch)

[PhillipsOwen]

i noticed odd behavior with the new "select all" and "delete" buttons in the selected layers area. steps to reproduce:

• open app
• hit the select all and then the delete button to clear the layer list
• filter dialog
  • select options synoptic, todays date and then hit the search button
  • add the top 2 layers shown.
  • close the filter dialog
• hit the delete button without selecting a list item to delete.
• note that the first item disappears without actually selecting something to delete.

part 2:

• go back to the filter dialog
  • use the same filtering criteria noted above.
• note that the top two items are already pre-selected.
  • would expect only 1 to be pre-selected as one was previously removed in the steps above.
