purchase_windows_spec: Add feature spec for destroy

Check that `PurchaseWindow`s can be destroyed, starting from the
`#index` page.

Update the i18n key used in the decorator to get the text that appears
in the alert when destroying a `PurchaseWindow` so that it correctly
corresponds to the one used in the locale file.
