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。

Target

• I checked that the commit is targeting the correct branch (note that Camel 3 uses camel-3.x, whereas Camel 4 uses the main branch)

Tracking

• If this is a large change, bug fix, or code improvement, I checked there is a JIRA issue filed for the change (usually before you start working on it).

Apache Camel coding standards and style

• I checked that each commit in the pull request has a meaningful subject line and body.

• I have run mvn clean install -DskipTests locally and I have committed all auto-generated changes
