[#1251] Refactor test_create.py

I just changed the test names and modified to call assert_raises instead of
nose.tools.assert_raises.
Merge branch '1251-resource-view' into 1792-filterable-resource-views
[#1792] Add filters to the filterable resource view's schemas

We add filter_fields and filter_values fields to their schema, and also convert
them to a single filters dict, to make it easier for the rest of our code.
[#1792] Don't require "title" on resource_view_update

We just require the ResourceView's id.
[#1792] resource_view_update works with filter_fields and filter_values

As added for resource_view_create on e5e0e15, this does the same for
resource_view_update.
