Inconsistent mediaType/s handling

[ivan-kovatchev]

The JSON-LD spec uses the following accept header:

Accept: application/ld+json;profile=http://www.w3.org/ns/json-ld#expanded

When I try to use negotiator with this accept header, I'm seeing the following behaviour:

negotiator.mediaType() is application/ld+json
negotiator.mediaType(["application/ld+json"]) is undefined

negotiator.mediaType without the parameter is correct, but negotiator.mediaType with the parameter is incorrect.

This is probably linked to the profile parameter, as adding another MIME type after that works correctly:

Accept: application/ld+json;profile=http://www.w3.org/ns/json-ld#expanded, application/n-quads

negotiator.mediaTypes() is [ 'application/ld+json', 'application/n-quads' ]
negotiator.mediaTypes(["application/n-quads"]) is [ 'application/n-quads' ]
