incorrect french tokenization and tagging for c'est

**Language**
French

**Describe the bug**

"C'est" is tagged by catalyst as (token, lemma, pos): 

```
C None NOUN
' None PUNCT
est None AUX
```

and by spacy using fr_core_news_lg as:

```
C' ce PRON
est être AUX
```

**Expected behavior**

Contracted forms like `C'` should match the spacy output and common verbs like `est` should include their lemma.
