openpgp: invalid argument: cannot encrypt because recipient set shares no common algorithms

Seeing the following:

```
$ keybase -version
keybase version 1.0.14-1
$ keybase pgp encrypt spiros -m "Test"
▶ ERROR openpgp: invalid argument: cannot encrypt because recipient set shares no common algorithms
```

If I run this key through gpg locally, I can send and receive messages just fine.

Start by reproducing the reported `keybase pgp encrypt spiros -m "Test"` command and compare its recipient capabilities with the locally working gpg behavior. Done means identifying the incompatible algorithm set and making encryption succeed for this recipient, with a regression check for the reported command.
