Ed Page 4b7ed54d7e test(derive): Provide better error info 
`Parser::parse_from` will call `exit` on failure and we don't just lose
backtrace information but we don't even know which of the tests running
in parallel panicked.  I ran into this when experimenting with
`clap_derive` and I couldn't tell what actually failed.

So let's switch to `Parse::try_parse_from`.

Errors went from:
```
test option_option ... ok
error: Found argument 'bar' which wasn't expected, or isn't valid in this context

USAGE:
    clap_derive [OPTIONS]

For more information try --help
error: test failed, to rerun pass '--test arg_enum'
```
To:
```
test option_option ... ok
test variant_with_defined_casing ... ok
test skip_variant ... ok
test default_value ... ok
test vector ... FAILED
test option_vector ... ok

failures:

---- vector stdout ----
thread 'vector' panicked at 'called `Result::unwrap()` on an `Err` value: Error { message: Formatted(Colorizer { use_stderr: true, color_when: Auto
, pieces: [("error:", Some(Red)), (" ", None), ("Found argument '", None), ("bar", Some(Yellow)), ("' which wasn't expected, or isn't valid in this
 context", None), ("\n\n", None), ("USAGE:\n    clap_derive [OPTIONS]", None), ("\n\nFor more information try ", None), ("--help", Some(Green)), ("

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

failures:
    vector
