Fix getAt(i) for Second Test Case Expect

In a prior commit, in 'loads multple datas from an api' function,  getAt(1)
for the second test case expect was accidentally changed to getAt(0).  Because
there are two tests cases in this function, the second test case expect should
use getAt(1). This commit reverts getAt(0) back to getAt(1) for the second test
case expect.
Remove conflict resolution annotations

In a prior conflict resolution, the "========" and other related annotations
were left in the app/controller/List.js file and the conflict never resolved.
This commit resolves the conflict and removes said annotation from the file.
Re-include store query configs: pageParam, limitParam, startParam

Prior to this branch, we were using locally-stored JSON sample data
for app tests. This branch updates stores to fetch API data, however
the default query includes unnecessary parameters. This commit
re-introduces pageParam, limitParam, and startParam to the Vendor,
Product and Location stores to correct these query defaults.
Update Location and Vendor stores to point at staging API endpoints.

Prior to this commit, all data in the app had been fetched from sample
.json files. This commit points the Locations.js and Vendors.js stores
to the correct API endpoints and updates the corresponding store tests
in Jasmine.

This update implies further work:
- Fix stores to include a "empty" selection such as "please choose a product"
- implement autoload callbacks.
- Update the Location model to match the API output
