Present proof problem report handler throws exception for OOB proof requests

[loneil]

When an abandoned state triggers on a 2.0 proof (in our BC Gov VCAuth-N ecosystem implementation, when a user declines the proof in their wallet) it invokes the V20PresProblemReportHandler. But if this is an OOB proof request with no connection an unhandled exception happens due to context.connection_record.connection_id

This was addressed for the 1.0 protocol here #2723 but I think should be added for the equivalent problem report handler for 2.0

Addressed here #3068

@Gavinok @esune as discussed the issue with VCAuth-N erroring on decline with 2.0 proofs.
