find logfiles throwing error

Logfiles that have characters in the filename are throwing errors during compile of `bin/start.sh` https://github.com/mrdavidlaing/stackato-buildpack-wordpress/blob/master/bin/compile#L218

error:
```bash
find: paths must precede expression: phpdoc-1380560584.log
Usage: find [-H] [-L] [-P] [-Olevel] [-D help|tree|search|stat|rates|opt|exec] [path...] [expression]
rake aborted!
```

This was noticed with `phpdoc`, that uses log files in the format ` phpdoc-1380560584.errors.log` and ` phpdoc-1380560584.log`
