Set inverse_of for Project/Services relation

## What does this MR do?

This MR adds the `inverse_of:` option to two associations to reduce the number of queries when running code such as ` project.gitlab_issue_tracker_service.project`.

## Are there points in the code the reviewer needs to double check?

No.

## Why was this MR needed?

In !4410 it was revealed code such as the above is used and would run SQL queries when the root object (usually a Project) was already present. By using `inverse_of` Rails can just re-use those Project instances.

## What are the relevant issue numbers?

None.

This ensures that code such as this don't run needless SQL queries:

    project.gitlab_issue_tracker_service.project

This also means that if the root `project` eager loads any associations
the Service object will be able to re-use those.

Resolve "Option to disallow author to approve merge request"

This prevents an MR from being approved by the author of the MR. The
author won't see the approve MR button, and if they try via the internal
or public API, it will fail.

Closes #388.

Eager load project relations in IssueParser

## What does this MR do?

This changes the ReferenceParser class to eager load various associations. This in turn results in the permissions checking code (e.g. the `Ability` model) to _not_ run dozens if not hundreds of extra SQL queries depending on the amount of references involved (in a single document).

## Are there points in the code the reviewer needs to double check?

No.

## Why was this MR needed?

In !4410 it was revealed a _lot_ of a queries came from the `Ability` model and the code it would call. In many cases this was because the code would simply get a project, then get the owners; or get a group, then get some association of that. Eager loading these associations is a fairly simple solution and greatly cuts down the number of queries.

## What are the relevant issue numbers?

None.
