Bug 31054: Manual importing for EDIFACT invoices fails with a 500 error page

Error in plack log is: Can't locate object method "new" via package
"Koha::Plugin::Com::ByWaterSolutions::MyEdifactPlugin" (perhaps you
forgot to load "Koha::Plugin::Com::ByWaterSolutions::MyEdifactPlugin"?)
at /usr/share/koha/lib/Koha/EDI.pm line 219.

Test Plan:
1) Set EdifactInvoiceImport to "Don't"
2) Configure an EDI vendor to use an EDIFACT plugin
3) Attempt to import an invoice file
4) You will be shown an error page
5) Apply this patch
6) Restart all the things!
7) Attempt to import another invoice file
8) It works!
