track_caller on custom assert functions

[kornelski]

This makes test helper functions point to the failing test, rather than internals of a function that did some checking.

Good call.

I don't get why the "homu" test failed. The log only shows:

Run exit 1
  exit 1
  shell: /usr/bin/bash --noprofile --norc -e -o pipefail {0}
Error: Process completed with exit code 1.
