    Reland "[AutofillAi] Walletable Entities have icon and link in management page"

    This reverts commit 8a098e225d05ed2977b03214bd5b798bd81230c0.

    Reason for revert: The issue with the original CL was likely that
    the test was not taking into account the difference between
    branded an non-branded builds. The branded builds uses an internal
    Google Wallet icon, while the non-branded one uses a placeholder
    string. The test is now fixed to check for a shared element
    (icon button) that exists in both branded and non-branded builds.
