Bug 13199: Test incoherence between 'en' sample notices and translated notices

This test identifies incoherences between translated sample notices and the
'en' reference file.

Koha sample notices are loaded to 'letter' table from a text SQL file
during Koha installation by web installer. The reference file is the one
provided for English (en) installation :

  <koha_root>/installer/data/mysql/en/mandatory/sample_notices.sql

Alternatives files are provided for other languages. Those files are difficult
to keep synchronized with reference file. This could be an functional issue
since some Koha operation depend on notice existence, for example Print Slip in
Circulation.
