CookieStore: Fix Flaky WPT Test for getSubscriptions

This test fails because the cleanup to "unsubscribe" cookies would
occur after the registration has already been unregistered for
non-workers.  This change removes the cleanup to "unsubscribe" and
just relies on "unregister" for cleanup.

The flaky failures can be reproduced locally using the following gn args
and commandline. (Googlers: http://screen/E7px76cVS2E)

gn args:
dcheck_always_on = true
ffmpeg_branding = "Chrome"
is_component_build = false
is_debug = false
mac_deterministic_build = true
proprietary_codecs = true
symbol_level = 1
use_goma = true

command: python third_party/blink/tools/run_web_tests.py -t LinuxTest third_party/blink/web_tests/external/wpt/cookie-store/cookieStoreManager_getSubscriptions_multiple.tentative.https.any.js --gtest_repeat=20
