fix: issue2550962. remove assert in Role::hasPermission issue2550962 - Check uses of assert in roundup code. An assert was used to make sure that a classname always accompoanied an itemid in hasPermission. The Security::hasPErmission has an if clause that does the same check and raises a ValueError. Remove asserts because they ae removed when running python in optimized mode.

try:
    from html import escape as html_escape_  # python 3

    def html_escape(string, quote=False):
        # html_escape under python 3 sets quote to true by default
        # make it python 2 compatible
        return html_escape_(string, quote=quote)
except ImportError:
    # python 2 fallback
    from cgi import escape as html_escape  # noqa: F401
