Throw error if incorrect data on triplestore.insert

[srosset81]

If I call triplestore.insert with incorrect data (without a context allowing to map id to @id):

{
  id: 'http://localhost:3000/elisa/data/ed9e4a60-e54d-45f7-bed2-0fe3a4ed1807',
  type: 'Note',
  'dc:created': '2024-06-20T15:05:46.934Z',
  'dc:creator': 'http://localhost:3000/elisa',
  'dc:modified': '2024-06-20T15:05:46.934Z',
  attributedTo: 'http://localhost:3000/elisa',
  content: 'Hello',
  context: 'http://localhost:3000/elisa/data/723d1618-7a6d-4d01-8581-4469d4fcbb9a',
}

... the JSON-LD parser will convert it to these triples:

_:b0 <dc:created> "2024-06-20T15:05:46.934Z" .
_:b0 <dc:creator> "http://localhost:3000/elisa" .
_:b0 <dc:modified> "2024-06-20T15:05:46.934Z"

In the end, nothing will be inserted at all.

The problem is that an error should be thrown to be aware there was a problem.

Fixed here 70fc2d7

I'm now throwing an error on the jsonld.parser.toRDF action if no JSON-LD context is found.
