Bug 36392: (bug 34219 follow-up) Fix getAll for vendors - ERM

In commit f1078daf8f
   Bug 34219: Allow getAll to receive additional URL parameters

We needed to call getAll instead of get to fetch all the vendors

Test plan:
Have more than 20 vendors and create/edit an agreement.
Notice that the vendor list contains all the vendors
