Fix foreign key = 0 not fetching related object

Introduction

Fixes fetching relations with foreign key = 0.
Currently inside eagerPair-method the foreign keys are just checked for being falsy,
leaving the related instance out of the parent's relations if the FK is 0.

Fixes #1685.

Motivation

This PR enables fetching relations with value 0 as the foreign key.

Proposed solution

Compare the groupedKey-variable (which stores the foreign key) through lodashes isNil-method inside the if-block, instead of just checking for a falsy value. This way 0 is a valid value, but null / undefined values are not.

Is there any possibility of groupedKey ever being undefined?

@ollija Can you add some tests to check for this? I'm asking because there was already a much earlier issue exactly like this one that was deemed fixed (#49), but it must have regressed at some point. I would like to prevent that from happening again in the future.
