Link relation and path configured with @RestResource ignored for content properties with multiple capital letters

[vierbergenlars]

Describe the bug

This looks like a similar bug as #1146, except now applied to to RestResourceMappingBuilder instead of ContentPropertyMappingContextVisitor.

To Reproduce

Given a JPA entity with a @RestResource annotation:

@Entity
@NoArgsConstructor
@Getter
@Setter
public class Person {
	@Id
	@GeneratedValue(strategy = GenerationType.AUTO)
	@JsonProperty(access = JsonProperty.Access.READ_ONLY)
	private UUID id;

	private String name;

	@RestResource(linkRel = "d:mugshot")
	@ContentId
	@JsonIgnore
	private String mugshotId;

	@ContentLength
	@JsonProperty(access = JsonProperty.Access.READ_ONLY, value = "mugshot_length")
	private Long mugshotLength;

	@MimeType
	@JsonProperty("mugshot_mimetype")
	private String mugshotMimetype;

	@OriginalFileName
	@JsonProperty("mugshot_filename")
	private String mugshotFilename;

	@RestResource(linkRel = "d:idcard_front", path = "idcard-front")
	@ContentId
	@JsonIgnore
	private String idcardFrontId;

	@ContentLength
	@JsonProperty(access = JsonProperty.Access.READ_ONLY, value = "idcard_front_length")
	private Long idcardFrontLength;

	@MimeType
	@JsonProperty("idcard_front_mimetype")
	private String idcardFrontMimetype;

	@OriginalFileName
	@JsonProperty("idcard_front_filename")
	private String idcardFrontFilename;

	@RestResource(linkRel = "d:idcard_back", path = "idcard-back")
	@ContentId
	@JsonIgnore
	private String idcardBackId;

	@ContentLength
	@JsonProperty(access = JsonProperty.Access.READ_ONLY, value = "idcard_back_length")
	private Long idcardBackLength;

	@MimeType
	@JsonProperty("idcard_back_mimetype")
	private String idcardBackMimetype;

	@OriginalFileName
	@JsonProperty("idcard_back_filename")
	private String idcardBackFilename;
}

Steps to reproduce the behavior:

1. Create a spring-content application with this entity
2. Create a new Person instance with POST /persons with an empty object
3. Notice that in the returned JSON, the link relation and path as specified in @RestResource is not taken into account, it falls back to the default instead. (Note that the annotation does take effect for the "mugshot" content property

Expected behavior

Of course, I expect the settings set in the @RestResource annotations to take effect

If applicable, add screenshots to help explain your problem.

Additional context

I believe the fix is to use the same function used in ContentPropertyMappingContextVisitor in RestResourceMappingBuilder.
