Description

Endpoint URI must contain a parametr otherwise method FacebookEndpoint#initState will not be called. This results in the following exception:

Caused by: java.lang.NullPointerException
	at java.util.Collections$UnmodifiableCollection.<init>(Collections.java:1026)[:1.8.0_45]
	at java.util.Collections$UnmodifiableList.<init>(Collections.java:1302)[:1.8.0_45]
	at java.util.Collections.unmodifiableList(Collections.java:1287)[:1.8.0_45]
	at org.apache.camel.component.facebook.FacebookEndpoint.getCandidates(FacebookEndpoint.java:186)

This behaviour is not correct because it is not possible easily change endpoint parameter values.

We should support the following usecase:
header: CamelFacebook.userId = xxxxx

<to uri="facebook://user"/>

and not only:

<to uri="facebook://user?userId=xxxxx"/>
