CAMEL-19859: camel-spring-rabbitmq set headerfilter not effective

[TUCJVXCB]

Description

if i use java code to config spring-rabbitmq component headerfilterstrategy, the doinit() method of SpringRabbitMQComponent will be executed before i config headerfilterstrategy, so the DefaultMessagePropertiesConverter may reference headerfilterStrategy the old value。
