Title: Show error details when failing to parse project json file

Small change to display the error details when the project json is malformed. Without the patch the error message looks like this:

```ValueError: Error parsing spider (invalid JSON): project.json```

With the patch looks like this:

```ValueError: Error parsing spider (invalid JSON): project.json: Expecting object: line 9 column 5 (char 964)```
