Dkg panic when trying to dkg with your own self

I start one fedimintd, configure federation of size 2, click submit, past the connection string I get as the connection string of the peer, push submit and fedimintd crashes:

thread 'tokio-runtime-worker' panicked at 'assertion failed: `(left == right)`
  left: `G1Projective { x: 0x113ff8542c7dc3e660b0d8b755b43af7b6a974e7b83b8d66b24c595ac24cd20ee1d59855915078acc88dbacbed139aac, y: 0x048a22a2246bbcbab66e4bb36750771a63c9a84069aff50faa026b2ee4cbf9a21a96cdcb064a2e71589d3040e5724ee3, z: 0x01a5b3aac38dad0e654f16a22c98ac9ab2ba8339b29149b4b0e9c5dec195dff3bc5ad01c7e777e26d5193ae73a164567 }`,

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Looking at the code we should probably remove all these asserts and replace them with ensure. Panics bad, Results good.

Another one (truncated hex string in the connection string)
