[CCExtractor-Web] Add some unit tests
Introduction
CCExtractor-Web is a web application for subtitle extraction through CCExtractor and is one of our Google Summer of Code 2018 projects. The project provides a simple interface for users, right in their web browser to upload their files and get subtitle files from any device without actually installing CCExtractor.

The task
Currently, there are a limited set of unit/integration tests. We'd like to increase coverage, so more tests should be added. Flask provides a way to test the application, so it'd be great to make use of that and test some stuff that way.
Requirements to complete this task
We expect an opened pull request, which contains the modification requested above, unit tests that cover (most of) the changes, and documentation where necessary.
