Disable authencation to get user's followers

[yashwanth2804]

do we really need authentication to see followers of some other user's . while in twitter also we can see user's followers even without following.

describe "GET /api/followers" do
    before do
      follower.follow user
      user.reload
    end

    context "when user is unauthorized" do
      it "does not return user followers list" do
        get users_api_followers_path
        expect(response.body).not_to include follower.name
      end
    end

    context "when user is authorized" do
      it "returns user followers list" do
        sign_in user
        get users_api_followers_path
        expect(response.body).to include follower.name
      end
