Updates several tests to explicitly disable the quota info cache by setting
dom.quotaManager.loadQuotaFromCache to false.
These tests were previously relying on origin access time updates (which set
the "accessed" flag) to trigger full origin scans. This behavior was a side
effect rather than an intentional part of the test logic.
Disabling the quota info cache ensures these tests do not depend on unrelated
behavior and continue to pass even when access time updates are disabled via
the dom.quotaManager.temporaryStorage.updateOriginAccessTime pref.
This is a follow-up to the patch that added the pref for manual testing.
