Language Data Notes

language data when added through the current editProfilePane doesn't seem to be written correctly. Plus there are a couple ways of storing data documented in another issue. Handled by selecting based on all 3 ways,
Note: if I am correct then socialaccounts have the same issue

after doing lots of copiloting research

<#person> schema:knowsLanguage _:b1 .

First list node
_:b1 rdf:first <#id1775784472913> ;
     rdf:rest _:b2 .

Second list node
_:b2 rdf:first <#id1775784742094> ;
     rdf:rest rdf:nil .

The actual language objects

I am writing the data the last way, if a user has data stored the other way it will read it, delete the old way of storing the data and add it storing it the new way. This really needs to be tested and reviewed.

Start by tracing language-data handling in the current editProfilePane and compare it with the three RDF storage forms shown in the issue. Verify reading each form, deleting the old representation, and writing the final list-node form; also check whether socialaccounts has the same problem. The issue names no files or tests, so identify the relevant test entry point before changing behavior.
