Issue displaying languages and social accounts

[timea-solid]

We have a few cases where a profile contains an ordered list of known languages. In this case we have an error like:
Uncaught (in promise) TypeError: languagesInStore.map is not a function
presentCV CVPresenter.js:94
ProfileView ProfileView.js:41
render index.js:45
promise callbackrender index.js:44
propertyTable manager.js:690
promise callbackpropertyTable manager.js:684
render manager.js:1659

This occurs is in the profile we have the following turtle:

:me schema:knowsLanguage :b5591_n3-4373, :b5591_n3-4374 ;

:b5591_n3-4373 <http://www.w3.org/1999/02/22-rdf-syntax-ns#first> :id1621179872094;
    <http://www.w3.org/1999/02/22-rdf-syntax-ns#rest> :b5591_n3-4374.
:b5591_n3-4374 <http://www.w3.org/1999/02/22-rdf-syntax-ns#first> :id1621182189397;
    <http://www.w3.org/1999/02/22-rdf-syntax-ns#rest> :b5591_n3-000.

:id1621179872094 solid:publicId l:fr.

:id1621182189397 solid:publicId l:de.

But we still have profiles that also contain:

:me  schema:knowsLanguage ( :id1621182189390 );
:id1621182189390 solid:publicId l:es.

So we need to handle both cases.
Attention, this can also occur for social media accounts. We need to improve both code places.

More info: it seems that in the move from NSS to CSS we moved from :me schema:knowsLanguage ( :id1621182189390 );
to the ```
:me schema:knowsLanguage :b5591_n3-4373, :b5591_n3-4374 ;

:b5591_n3-4373 http://www.w3.org/1999/02/22-rdf-syntax-ns#first :id1621179872094;
http://www.w3.org/1999/02/22-rdf-syntax-ns#rest :b5591_n3-4374.
:b5591_n3-4374 http://www.w3.org/1999/02/22-rdf-syntax-ns#first :id1621182189397;
http://www.w3.org/1999/02/22-rdf-syntax-ns#rest :b5591_n3-000.

format.
So we need to be able to parse both. The underlying PR fixes these issues.

Migration did not changed data.
The issue is between N3.js and rdflib.js
I remember seeing something in rdflib PRs relating to ordered lists.

Now it creates duplicates...
