Expected behaviour

When saving a filter with an expiry other than "never", clicking to edit the filter should show the original expiry that was selected when first saving the filter.

Actual behaviour

Clicking to edit a filter shows the expiry "never" every time, no matter which expiry you selected and saved originally.

Steps to reproduce the problem

1. Make new filter with the expiry "one week".
2. Save.
3. In the filtered words list, click "edit" next to the filter you just saved.
4. Expiry is "never".
