Agreements: in the new Agreement Line pane, display default coverage when looking up an e-resource

When creating a new agreement line and an e-resource which has default coverage is linked, the default coverage should be displayed as well as the e-resource card. Currently no default coverage is displayed.

The steps in the process would be:

1. User views an Agreement
2. Selects "Add agreement line"
3. In the "New agreement line" pane the user selects an e-resource from the basket
4. Then the button "Link selected e-resource". The e-resource is a journal with default coverage.
5. The e-resource card is displayed and the default coverage for the e-resource is also displayed.
