Issue #3386085: Prevent warning when str_starts_with() receives NULL route...

Zeeshan khanrequested to merge
issue/drupal-3386085:3386085-null-route-name-str-starts-with-v2 into main

  • Removed the kernel test (ExposedFormRenderTest) — NullRouteMatch injection doesn't simulate BigPipe's actual execution context

    • Added functional test testExposedBlockOnUnroutedRequestWithBigPipe() to ExposedFormTest.php which:
      • Installs big_pipe via module installer
      • Places views_exposed_filter_block:test_exposed_block-page_1 on all pages
      • Logs in as an authenticated user (BigPipe only activates for logged-in users)
      • Navigates to a non-existent URL (404)
      • Asserts the response is a 404 — not a 500 from an unhandled exception

    This directly follows the steps to reproduce from the issue summary with BigPipe installed, exactly as alexpott requested.
