fix: expectations and exclusions in tutorial 102 - NGSI-LD - Working with context

[bobeal]

• terms used as values in the address property (streetAddress, ...) are not in ngsi-context.jsonld. thus, when they are created with this context, they are expanded using the default vocab from the core context (https://uri.etsi.org/ngsi-ld/default-context/streetAddress and not https://schema.org/streetAddress) and when compacting without specifying a context, they are "correctly" compacted (streetAddress). See this link for a demo in the JSON-LD playground.
• when using the json-context.jsonld context, https://schema.org/name and https://uri.fiware.org/ns/dataModels#category are respectively compacted to schema:name and fiware:category. See this link for a demo in the JSON-LD playground
• different version of the core context used by a context broker raises error. added exclusions on this field, but there may be better ways to handle this.

I was working on those tutorials to improve the execution and resolve some issues. At the moment, I prefer to check the @context because I found some discrepancies.

Keep in mind that we are testing the tutorials not the functionality of the brokers.

The first two points of the PR are strictly about NGSI-LD compliance, nothing related with the brokers.

And you are testing the tutorials ... using context brokers. So it is a bit harsh to consider a broker is failing whereas it is just not using the same default version of the core context.
