As pointed out in this issue elixir-crawly#224, `GenServer.call(__MODULE__, {:pop, Elixir.Homebase})`, which is invoked from the worker.ex [here](https://github.com/elixir-crawly/crawly/blob/13fe05b400db46716729bd15e4ef1b67d12db5ee/lib/crawly/worker.ex#L40), returns the value `:ok`, shortly after starting the spider. With this change, the worker treats the returned `:ok` value similar to a returned `nil`, and waits for a request to be available.
