fix: memory leak in module cache management, fixes #560

[theKashey]

Summary

smartRequire is cleaning the cache before requiring module, and that might keep reference to an older version, causing a memory leak.

Fix

• remove module from the cache
• (added) remove module from parent.children
• (added) remove module from children.parent

Test plan

The algorithm is borrowed from rewiremock

@theKashey When will this fixed be released? We are having this issue too but it seems it was not released yet. Do we have an ETA?

[theKashey]

I will try to arrange a new release this weekends. There is one more important PR to merge before everything.
