[Fix] Fetch when vector id string contains spaces

[jhamon]

Problem

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

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

• Bug fix (non-breaking change which fixes an issue)

total nit, but it just be simpler to do something like return booleanish + script_injection + unwanted_interpolation, instead of calling ids.extend mult times?
