Bug 32779: ERM - Fix import from list

Bug 32779: ERM - Fix import from list

There is a typo, '$' is missing, which caused the following error:
Use of inherited AUTOLOAD for non-method Koha::BackgroundJob::CreateEHoldingsFromBiblios::fix_coverage() is no longer allowed at /kohadevbox/koha/Koha/BackgroundJob/CreateEHoldingsFromBiblios.pm line 126

Test plan:
Create a list, add an item
Turn on ERM
Create a package
Go to /cgi-bin/koha/erm/eholdings/local/titles
Click "Import from list"
Select the package, then your list, and import
It should succeed
