HTTP Client Upgrade Handler Compare Issue

Motivation:
The HttpClientUpgradeHandler attempts to compare a supported codec against the input codec but the comparison logic is reversed.

Modification:
Negate the logic in HttpClientUpgradeHandler so an error is detected in the error condition.

Result:
HttpClientUpgradeHandler should not fail the upgrade when the input protocol is valid.
