Perform a check within pre-find Mongoose Middleware

[ijemmao]

Background

There's a number of locations in the controller files that perform a "related collection check" to see if an associated WordSuggestion, ExampleSuggestion, or GenericWord already exist before attempting to create a new Word or Example document.

The Problem

These checks should happen with a Mongoose pre-find middleware so that logic doesn't muddy up the words.js and examples.js controllers files. The related WordSuggestion, ExampleSuggestion, and GenericWord ids are later used to update their merge properties with the following utils function: https://github.com/ijemmao/igbo_api/blob/master/src/controllers/utils/index.js#L95-L99
