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:
    # Python 3+
    from ssl import SSLError
except (ImportError, AttributeError):
    # Python 2.5-2.7
    from socket import sslerror as SSLError  # noqa: F401
