test(service-worker): fix default value of Request#credentials (omit --> same-origin) (#47260)

gkalpak · AndrewKushnir · commit f5cfbe00df5b · 2022-09-06T10:03:13.000-07:00
Previously, the default value of `MockRequest#credentials` (used in testing) was set to `omit`. This was different than the default value used in browsers, which is `same-origin` (see [Request docs on MDN][1]) and could lead to incorrect test results. This commit changes the default value for `credentials` to `same-origin` to match what would happen in the browser.
