dev/drupal#52 Partial fix for Deprecated q variable

[mlutfy]

Overview

In Drupal8, the 'q' variable is deprecated. This caused various warnings since the recent introduction of isFrontEndPage (68e3bc3).

Example: https://www.drupal.org/project/webform_civicrm/issues/3080284

Before

Annoying PHP notices.

After

No more notices.

Comments

This is only a partial fix to hush the notices. To fully support scenarios that have traditionally relied on q, we still need to create a patch for getUrlPath as described in https://lab.civicrm.org/dev/drupal/issues/52

This is a resubmission of #15265 to the RC branch.
