Avoid using project.name for ignored projects check

We can also use `getPath()` to replace `getName()` here.

> The project's name is not necessarily unique within a project hierarchy. You should use the getPath() method for a unique identifier for the project.

See https://docs.gradle.org/current/javadoc/org/gradle/api/Project.html#getName().
