Title: output "No synth app detected"  in non-synth-app directory

Thrown error in requiring `back/back-app` was not catched.
So error message was such a mess.

```
$ synth s

module.js:340
throw err;
^
Error: Cannot find module '/home/kumagi/back/back-app'

```

It should be

```
$ synth s
No synth app detected.
```

Thanks.
