Bug 33941: Fix wrong URL name in EBSCOPackagesList

This patch fixes a URL pointing to the wrong route which stops filtering from working in the table.

Note: To test you will need some EBSCO credentials

Test plan:
1) In ERM, go to EBSCO > Packages and search for a package
2) It should fail with a warning in the console saying that a required param "package_id" is missing
3) Apply patch
4) Repeat step 1
5) It should now successfully fetch packages
