I tested each installer file by deleting all notices from letter, running
the file and counting the records. I did so with and without this patch.
The results below show that in each case two notices were added as
expected. Note that the English file contains 25 notices including the two
new ones.

de-DE/mandatory/sample_notices.sql: 23 notices
es-ES/mandatory/sample_notices.sql: 18 notices
