ICE: trimmed_def_paths constructed but no error emitted

[saethlin]

ICE with cargo test in openpgp-ca v0.12.0

I just noticed the error actually says openpgp-card at the bottom, perhaps compilation doesn't even get to the final crate. In any case, I'm no good at minimizing these things, so I'm handing this off to people who are good at that.

Line 81 in b5c8c32

target_principal: target_principal.to_string(),

-                target_principal: target_principal.to_string(),
+                target_principal: with_no_trimmed_paths!(target_principal.to_string()),

This fixes the ICE, although I'm not sure if that's the right approach
