Resolve CoreNLP Regression

[tomaarsen]

Hello!

Pull request overview

• Add json "strict" parameter to CoreNLP #2993 introduced strict_json in CoreNLPServer, but tries to use it in GenericCoreNLPParser.

How to reproduce

from nltk.parse.corenlp import CoreNLPServer, CoreNLPParser

with CoreNLPServer() as server:
    sentence = "This is my sentence, which I'd like to get parsed."
    parser = CoreNLPParser(server.url)
    next(parser.parse_text(sentence)).pretty_print()

Before this PR

Traceback (most recent call last):
  File "c:\GitHub\nltk\nltk_0002.py", line 6, in <module>
    next(parser.parse_text(sentence)).pretty_print()
  File "c:\GitHub\nltk\nltk\parse\corenlp.py", line 298, in parse_text
    parsed_data = self.api_call(text, *args, **kwargs)
  File "c:\GitHub\nltk\nltk\parse\corenlp.py", line 252, in api_call
    return response.json(strict=self.strict_json)
AttributeError: 'CoreNLPParser' object has no attribute 'strict_json'

This  is  my      sentence  ,  which  I    'd like  to     get     parsed  .

I've simply moved strict_json fully to GenericCoreNLPParser.
