Mock controller test with external call

[ajkiessl]

Here:

scholarsphere/spec/controllers/dashboard/collections_controller_spec.rb

Lines 5 to 15 in 720e747

	RSpec.describe Dashboard::CollectionsController, type: :controller do
	# TODO this appears to call identity API, we should mock this out
	# This was Adams access account. he left. tests started failing.
	let(:valid_attributes) {
	{
	'editors_form' => {
	'edit_users' => ['djb44']
	}
	}
	}

We need to mock this or it fails when the user leaves Penn State. Tests shouldn't be making external calls like this anyway.
