Nil pointer on build failure recovery

[jamesnetherton]

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]
	panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0x12c9b56]

This seems to be the problem. build.Status.Failure wont have been initialized at this point.
