security protocol ordering preference broken

[marten-seemann]

Since fx groups don't provide ordering (see https://pkg.go.dev/go.uber.org/fx#hdr-Value_Groups), we end up not adhering to the ordering of the configured security protocols.

We need to:

• fix this bug
• add an integration test

This is a blocker for the v0.24.0 release.

fx.... lol.

@vyzo Enjoy your told-you-so moment.

The fact that we didn't have any tests for security protocol selection is the real culprit here, as I see it.

it was a small triumph :)
