Bug 33466: Link to the vendor from the ERM module

There are 3 tables in the ERM module where we display the vendor name
but without a link to the acquisition module.

This patch adds the links.

Test plan:
Create an agreement, a license and a local package.
Pick a vendor and notice that now there is a link on the list view.
