[Fix] Fetch when vector id string contains spaces (#372)

## Problem

Some data operations fail when the vector id string contains a space.

```python
from pinecone import Pinecone

pc = Pinecone()
pc.fetch(ids=["id with string"]) # no results returned, even when vector exists
```

## Solution

The problem occurred due to the way spaces were being encoded as `+`
instead of `%20` in url query params. The fix was a small adjustment to
our code generation templates.

I added test coverage for upsert / query / fetch with various weird ids
to make sure the change in encoding hasn't broken any other use cases
that could pop up.

## Type of Change

- [x] Bug fix (non-breaking change which fixes an issue)
