Add path to executable in error

[mattscamp]

Returns the path to the exec that failed on error. Ref: #2529

Thanks for the PR! I wonder though if perhaps we should thread through the name of the test rather than the path to the executable? We could provide an error message along the lines of:

error: test failed, to rerun pass `--test foo`

That way we can handle failures like "pass --doc", "pass --lib", or "pass --test name-of-weird-thing"

Great idea. I will work on the changes. Thanks for the feedback!

ping @mattscamp, any update on this? (I can help out if needed)

Sorry, been caught up with work lately. If I remember right, I had this finished, except it doesn't work on inline tests that are not in their own files. So if I have inline tests, it returns "pass --{name of test}", but that doesn't actually work when you pass it because it's not the name of a test file. I will try to take a look today or push it to a branch for someone else to jump on it!

@mattscamp ok thanks for the update! And no worries if you're busy, was just curious :)
