Cannot add more fields to the ValidatedError

When I try this:

``` javascript
throw new ValidationError([{
name: 'projectId',
type: 'project-not-found',
value: projectId
}]);
```

It's complaining with this error:

```
{error: "validation-error", reason: "errors.0.value is not allowed by the schema", details: Array[1], message: "errors.0.value is not allowed by the schema [validation-error]", errorType: "Meteor.Error"…}
```

I'm using version `0.2.0` because it doesn't let me upgrade it because of `aldeed:simple-schema`

```
error: Conflict: Constraint mdg:validation-error@0.5.1 is not satisfied by mdg:validation-error 0.2.0.
Constraints on package "mdg:validation-error":
* mdg:validation-error@0.5.1 <- ppp:ppp-projects-validators 0.0.1 <- ppp:ppp-launch 0.0.1 <- ppp:ppp-app-editor 0.0.1
* mdg:validation-error@0.2.0 <- aldeed:simple-schema 1.5.3 <- mdg:validation-error 0.2.0 <- ppp:ppp-projects-validators 0.0.1 <-ppp:ppp-launch 0.0.1 <- ppp:ppp-app-editor 0.0.1
* mdg:validation-error@0.2.0 <- aldeed:simple-schema 1.5.3 <- ppp:ppp-launch 0.0.1 <- ppp:ppp-app-editor 0.0.1
```

Start by reproducing the ValidationError example with version 0.2.0 and inspect the validation schema that rejects errors.0.value. Check the aldeed:simple-schema dependency constraints shown in the issue. Done means the additional field is accepted without leaving the package version conflict unresolved.
