Convert entity relation name back to camel case before querying

[too-soon]

Fixes #28.

Sometimes an entity would not be found while trying to POST a resource with its relationship.
Like mentioned in the issue, we need to convert our entity name back to camel case before querying.

@Mites-G thanks for contribute. Could you add unit test for this case?

@klerick can you help me creating a new relationship on the mock database?

It needs to have an underline character(_) in its name to test my feature but I couldn't figure out how to do so.

Something to that effect:

  @OneToOne(() => Addresses, (item) => item.id)
  @IsNotEmpty()
  @JoinColumn({
    name: 'addresses_id',
  })
  public address_data: Addresses;

you shoukd create table using SQL in this file
and create entity for test and add reletion. and use it in test. I believe, create separate entity will better solution for unit test which cover this case.

if you have problem, let me know, tomorro I will have free time and will try to do it myself
