Issue:
Nil pointer on build failure recovery
I wanted to simulate a build failure so I did:

```
$ kamel run --dependency=camel-foobar examples/hello.xml
```

Which made the operator crash:

```
panic: runtime error: invalid memory address or nil pointer dereference [recovered]

[This](https://github.com/apache/camel-k/blob/master/pkg/controller/build/recovery.go#L100) seems to be the problem. `build.Status.Failure` wont have been initialized at this point.
