http.get() in init context causes nil pointer dereference panic

[na--]

Running this script:

import http from 'k6/http';

http.get("http://test.loadimpact.com");

export default function () {
	console.log("test");
}

panics with:

panic: runtime error: invalid memory address or nil pointer dereference [recovered]
	panic: Panic at 40: runtime error: invalid memory address or nil pointer dereference [recovered]
	panic: Panic at 40: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x120 pc=0xaa5915]
...

Not sure if we should allow http function calls in the init context at all, but either we have to show a nice error message or it should work.
