The syntax for language references dialects is incorrect (and syntactically illegal by BCP47)

This patch uses the correct syntax.

This bug prevents use of Ontoserver with the demonstrator

@alopezo this PR will break out demos until we make Snowstorm compatible with the
Ontoserver en-x-sctlang-00000000-00000000-00000000 language dialect format.
Currently we use en-X-0000000000000000. We should make Snowstorm work with both.

Thank you for the PR @lawley, it will take us some time to get this change into a Snowstorm release and into the production browser. Following the current deployment schedule the next deployment slot for new changes will be September.
Please fork the project in the mean time.

@kaicode do you think the snowstorm fix will be done soon? All of the values in national-language-metadata.json are incorrect and need to be updated to the <languageTag>-X-sctlang-<refsetId> format.

Status: Waiting for Snowstorm update to support the dashed format for ConceptIds in the language spec.
