run-tests.sh no longer respects specifying a port with the --url option

Updated: Comment #0

Problem/Motivation

Following #1888424: Make Drupal's URL generation logic available to HttpKernel, and minimize code repetition/divergence , the --url flag for run-tests.sh no longer works to specify a particular port. When tests are run, the port is ignored, and therefore any web tests that use the simpletest browser will fail because they are accessing the wrong URL. I'm not sure whether this also impacts other URL generation, but assuming it's related to our HttpKernel integration given the issue that introduced it.

Steps to reproduce

1. Install Drupal to run on a port other than the default port (e.g. 8888).
2. Enable simpletest.
3. Use run-tests.sh to run a web test against this site, e.g.:
   
   php ./core/scripts/run-tests.sh --verbose --url "http://localhost:8888/d8git" --class "Drupal\block\Tests\BlockTest"
4. Observe that the test will fail, and the verbose output indicates that the URL used does not include the port:
