I thought using a **mutable reference** may be better than returning the
`cache` struct, so that we don't need to worry about forgetting to
reassign `cache` in the future.

realted to #4898

Fixes the panic that happens after generating a HMR patch after syntax
error.

~~probably related to #4898,~~ found while trying
#4898 (comment)

This test fails only when tree shaking is enabled. Enabling tree shaking
with HMR is not supported and is disabled now. So I decided not to try
fixing it and only keep the tests for now.
