LP#1928275: fix the Angular "Copy Queue To Bucket"

Similar to bug 1934184, a blank routerLink on an anchor no longer
causes an ngbModal to open via a click handler.

To test
-------
[1] Create a MARC import bib queue that has at least one imported
    record it.
[2] Click the "Copy Queue To Bucket" link from the queue inspection page
    and observe that nothing happens.
[3] Apply the patch and repeat step 2. This time, the add-to-bucket dialog
    should appear.
