Flowable Spring Boot Starter Rest .zip file deployment

**Describe the bug**
I have an application that uses Flowable’s Spring Boot Starter Rest.

[pom.xml](https://github.com/Robinyo/serendipity-api/tree/master/projects/spring-boot):
```
...

org.flowable
flowable-spring-boot-starter-rest
${flowable.version}

org.flowable
flowable-ldap
${flowable.version}

...

```

If I place a **.zip** file in the default location (i.e., /resources/apps) the processes are successfully deployed. However, the associated forms are not deployed.

If I place a **.bpmn** file in the default location (i.e., /resources/processes) and the associated forms (**.json)** in the default location (i.e., /resources/forms). The processes are successfully deployed, however, the associated forms are not deployed.

**Expected behaviour**
That the processes and the associated forms are deployed.

Inizia con il pom.xml collegato e riproduci il deployment usando un .zip in /resources/apps; quindi confrontalo con un .bpmn in /resources/processes e con moduli .json in /resources/forms. Traccia l’entry point del deployment di Spring Boot Starter REST e verifica che vengano distribuiti sia il processo sia i moduli a esso associati.
