`excludesLints` in `WithoutLintsTest.java` passes even when nothing is excluded

The parameterized test excludesLints in src/test/java/org/eolang/lints/WithoutLintsTest.java:34 builds a WithoutLints over a single fake lint named ascii-only (line 41) and asks it to exclude unit-test-missing or unit-test-without-live-file (line 42). Neither name is in the list, so the assertion at line 44 only checks that ascii-only is not equal to the excluded name. That holds whatever WithoutLints does: if its filter handed the origin back untouched, the test would still be green.

The fixture drifted over several refactors, the last one in 235cda2d swapping in LtFake("ascii-only"), while the names in @ValueSource stayed the same.

Putting new WithoutLintsTest.LtFake(lid) into the fixture next to another fake, and asserting that lid is not among the remaining names, makes the test fail when exclusion stops working.

Start with the parameterized excludesLints test in src/test/java/org/eolang/lints/WithoutLintsTest.java, especially lines 34-44 and the LtFake fixture. Run this test before and after strengthening the fixture with another fake lint, then verify the assertion fails if an excluded lint remains and passes when exclusion works.
