src: fix crash on FSReqPromise destructor

We are deciding whether to end `fs` promises by checking
`can_call_into_js()` whereas in the `FSReqPromise` destructor we're
using the `is_stopping()` check. Though this may look as semantically
correct it has issues because though both values are modified before
termination on `Environment::ExitEnv()` and both are atomic they are not
syncronized together so it may happen that when reaching the destructor
`call_into_js` may be set to `false` whereas `is_stopping` remains
`false` causing the crash. Fix this by checking with
`can_call_into_js()` also in the destructor.
