Fix Windows CI failure in testGetRoutes: replace both \\r\\n and \\n newlines

On Windows, PHP_EOL is \\r\\n but the CLI library writes \\n to the
output file. The removeColors() helper converts \\r\\n→\\n, so using
str_replace(PHP_EOL, '') afterwards failed to strip those \\n on
Windows, leaving newlines in the haystack while the needle had none.

Fix: replace both \\r\\n and \\n so all newline variants are stripped
from both needle and haystack before comparison, making the test
platform-independent.
