Latest release does not contain updates made to SuggestionsAdapter

Some changes made to the library's SuggestionsAdapter such as this:

```
//changing the suggestions list to protected
protected List suggestions = new ArrayList<>();
```

..were not included in the latest `0.7.1` release. Please make a new release with these changes as we can't use the CustomSuggestionsAdapter implementation without the newly committed changes. Thanks!

Start by reviewing the SuggestionsAdapter changes referenced in the issue and the history of release 0.7.1. Check how the project publishes releases, then verify that the new release includes the protected suggestions list needed by CustomSuggestionsAdapter.
