Fix Bitbucket Server code annotations (#284)

In #237 the property names of the annotation model were changed to fix a bug with how code annotations are reported to Bitbucket Cloud. This PR however did not take into consideration that the previous naming was actually correct and required for Bitbucket Server. With this change Bitbucket Cloud will continue to receive the message as summary (API docs), while Bitbucket Server receives the message as message again (API docs).

The @JsonProperty annotations have been moved to the getters so that they support overrides, as mixing property-level and method-level annotations does not work for this use case. Technically this is only needed for the message property, but for consistency reasons this has been done for all fields and has been verified that this is mapped correctly for both cloud and server.
