This method invokes clear cache operations in proper order!!! Change method order cautiously!!!

The order is determined by cache dependency - gadget specs are retrieved from JiraI18nResolver that cache gadget specs values as well.

Gadget plugin uses under the hood the Shinding plugins that caches the gadget specs bundle request by default for 5min. Because of that cache invalidation is eventually consistent and gadgets for the user will be refreshed after 5min.

Caches hierarchy: JiraI18nResolver -> Shinding URL request cache (5 min expiration timeout) -> Shinding cache org.apache.shindig.common.cache.SoftExpiringCache (5 min expiration timeout) -> Gadget specs cache
