fix(tests): Update SourceFile test to reflect Line class refactoring

The `SourceFile` test was still referencing the `Line` class in its old, nested location. This has been corrected to reference the new, refactored `Coverband::Utils::Line` class.

This ensures that the tests for the `SourceFile` class are correctly referencing the refactored `Line` class, allowing the test suite to pass.
