Evaluation Script bugfix - Initalize Annotated Corpus as list [resolves

#70]

**Changes in `__main__.py`:**
* `load_annotated_corpus()` -> `load_annotated_corpus(return_iter=False)`.
**Reason:**
* Commit 29e3b56 adds return iteator functionality to `load_annotated_corpus`. Default is set `True`.
* Returned iterator is consumed by `for doc in tqdm(anno, unit=" doc", desc=f"Calculate n-dcg score for {name}"):`.
* After it is consumed it needs to be reset so that other summarizers can use `anno` but they did not.
* As a result only first summarizer in the list was evaluated and rest did not see a test data since the iterator was consumed.
* `anno` is now a list when the argument is set to `False`. Consume it as much as you wish.
