Micronaut: Method parameters should be resolvable in expression language

[dbalek]

Code completion for Micronaut Expression Language should be able to resolve parameters of the annotated method. For example param in the following snippet:

@XYZ("#{param.toUpperCase()}")
void test(String param);

Minor comment w.r.t. getting methods out of a group of Elements.
