NullPointerException on authentication failure with non-existent user and single plugin in AuthServer

[mrotteveel]

The code in WireConnection#getDefaultWireOperations() obtains the V10 protocol from protocols for processing the error, but with the default configuration in Jaybird 6, it won't contain the V10 protocol. Either obtain the lowest available version, or make sure to obtain V10 in a different way.

[mrotteveel]

Currently, we run the tests with all protocols enabled. We'll need to change that to run with the default, and skip tests that require a disabled protocol), or maybe explicitly enable the protocol for such a test, then we only need to enable unsupported protocols if we want to test against an unsupported version.

This is only reproducible if AuthServer has one property (e.g. AuthServer = Srp256).

[mrotteveel]

If the server has multiple authentication plugins, the failure happens after identify, and Jaybird will have a wire operations instance, so it doesn't need to create a "default" one.

[mrotteveel]

The protocol specific tests already behave correctly if enableProtocols is not set, so I'm changing the default enableProtocols from "*" (use all available) to not set (use only supported)
