Resource root listing links should have templated link to a resource [DATAREST-444]

Sri opened DATAREST-444 and commented

Currently resource root listing links only lists "self", "previous", "next" and "search" links. However it does not include a template link to a resource with href /resource/\{id\}.

Below is the code snippet that needed to be added to RespositoryEntityController

TemplateVariables variables = new TemplateVariables(new TemplateVariable("id", VariableType.PATH_VARIABLE));
Link resourceItemLink = new Link(new UriTemplate(entityLinks.linkFor(metadata.getDomainType()).withSelfRel().getHref(),
				variables), metadata.getItemResourceRel());
links.add(resourceItemLink);

However above code is not a complete fix since the links rendered is not form /resource/\{id\} but rather /resource. This is because TemplateVariables.toString() does not consider TemplateVariable.VariableType.PATH_VARIABLE in buiding the link.

If interested I could submit the patch in github

Affects: 2.2 RC1 (Evans), 2.2 GA (Evans), 2.2.1 (Evans SR1)
