cli: PR checkout: fully-qualified git refs unexpectedly received from the API

Describe the bug

It appears that having a remote pointer to the source of my fork (with any name) is making checking out a specific PR fail. Other PRs work so perhaps there is something strange about this branch, but I cannot figure out what.

❯ gh --version gh version 1.5.0 (2021-01-21) https://github.com/cli/cli/releases/tag/v1.5.0

Steps to reproduce the behavior

gh repo clone https://github.com/billwert/performance cd performance gh checkout 1654

Expected vs actual behavior

The PR checkout should succeed.
