Issue: xonsh: partially quoted values not completed correctly
Quotes are not removed from prefix if not completely enclosed by the engine and thus included in resulting values.
e.g. multiparts completion when adding a comma to an already quoted prefix:

```sh
carapace-bin/cmd/carapace on  master [$!] via 🐹 v1.17.1
❯ gh issue list --label 'good first issue',<TAB>

# ❯ gh issue list --label r'\'good first issue\',xonsh' 
```

```python
from xonsh.parsers.completion_context import *
CompletionContextParser().parse("gh issue list --label 'good first issue',", 8, None)

#CompletionContext(command=CommandContext(args=(CommandArg(value='gh', opening_quote='', closing_quote=''), CommandArg(value='list', opening_quote='', closing_quote=''), CommandArg(value='--label', opening_quote='', closing_quote=''), CommandArg(value="'good first issue',", opening_quote='', closing_quote='')), arg_index=1, prefix='issue', suffix='', opening_quote='', closing_quote='', is_after_closing_quote=False, subcmd_opening=''), python=PythonContext("gh issue list --label 'good first issue',", 8, is_sub_expression=False))
```
