python: Fix multiline quotes in a single line

An example case,
```python
mem_side_port = RequestPort(
    "This port sends requests and " "receives responses"
)
```

This is the residue of running the python formatter.
This is done by finding all tokens matching the regex `"\s"(?![.;"])`
and manually replacing them by empty strings.
