[PATCH v3 2/2] ssh signing: make sign/amend test more resilient

[Fabian Stelzer <fs@gigacodes.de>]

The test `amending already signed commit` is using git checkout to
select a specific commit to amend. In case an earlier test fails and
leaves behind a dirty index/worktree this test would fail as well.
Using `checkout -f` will avoid interference by most other tests.
