Reset runtime context options before releasing it back into pool

[lovromazgon]

This PR makes sure RuntimeContext options are reset before the context is returned to the pool.

It also adds a test case that fails without the change.

Fixes #499.

@goccy any chance you could look at the issue and PR? To me, it seems like a pretty straightforward fix.

@goccy I see you released 0.10.3, is there anything missing here that prevented you from including this PR?

[goccy]

I saw this PR, but I cannot accept this implementation.

[lovromazgon]

Can you elaborate? Do you have suggestions on other approaches to address this bug?

EDIT: I assume you're concerned about the allocation. How about the approach with setting the context to nil before releasing it?

[lovromazgon]

@goccy can I ask you to take another look at the PR and tell me if the current implementation is acceptable? 🙏
