…ram (#1266)

## Description of changes

*Summarize the changes made by this PR.*
 - Improvements
- Check if HttpClient is instantiated with inconsistent server and port
values, see #1261

## Test plan
*How are these changes tested?*
- [x] add tests for different HttpClient parameter scenarios
- [x] Tests pass locally with `pytest` for python, `yarn test` for js

## Documentation Changes
*Are all docstrings for user-facing APIs updated if required? Do we need
to make documentation changes in the [docs
repository](https://github.com/chroma-core/docs)?*

docstring is updated for settings, no docs update
