test: Don't rely on flash notice in system test
requested to merge 333055-spec-failure-in-spec-features-profile_spec-rb-profile-account-page-when-i-reset-feed-token into master
What does this MR do?
We already check that the previous feed token isn't present on the page anymore. That's enough. Relying on flash notices being present is an anti-pattern as flash notices aren't guaranteed to be there.
