Adding stream rule with 0 ID using API breaks server

Mongodb database cannot start properly after the API call which contains wrong type id.

## Expected Behavior

mongodb starts without errors

## Current Behavior

I receive the error
```
Unable to create injector, see the following errors: graylog
```

## Possible Solution

Adding api checks

## Steps to Reproduce (for bugs)

1. open Swagger
2. go to StreamRules
3. create a rule with content like
```json
{
"type": "0",
"value": "value1",
"field": "field1",
"inverted": "false",
"description": "super description"
}
```
4. restart database

## Context

of course after changing the wrong id in the database to correct value it starts working correctly.

## Your Environment

* Graylog Version: 3.1
* Elasticsearch Version: 6.8
* MongoDB Version: 3
* Operating System: Centos 7
* Browser version: Firefox 69.0
