[duplicated subtitle][unit test] Fix ./gradlew test --no-configuration-cache errors after moving from NewPipeExtractor to NewPipe repository.

- "error: static import only from classes and interfaces"
- Changed `package` and `import` statements to adapt to NewPipe main repository.
- Name 'containsDuplicatedEntries_exactDuplicate_shouldReturnTrue' must match pattern '^[a-z][a-zA-Z0-9]*$'.
- Variable 'expected' should be declared final.
- '+' should be on a new line.
- Line is longer than 100 characters
