Bug 1473380 [wpt PR 11782] - Unflake wpt/fetch/security/redirect-to-url-with-credentials.https.html, a=testonly

Automatic update from web-platform-testsUnflake wpt/fetch/security/redirect-to-url-with-credentials.https.html

The test is flaky because of step_timeout. This CL removes that, and
marks the test as consistent TIMEOUT.
