legendecas 7f496fefb6 report: fix missing section javascriptHeap on OOMError
`Environment::GetCurrent` may not available in the context of OOM.
Removes the cyclic `Environment::GetCurrent` and `env->isolate()`
calls to ensure both `isolate` and `env` is present if available.

However, this behavior is not guaranteed. As
`Environment::GetCurrent` didn't allocate new handles in the heap,
when a Context is entered it can still get the valid env pointer.
Removes the unstable assertion of the absence of env in the test.
