Added failing test for embedded belongsTo JSON serialisation
fix includeId typo for embedded belongsTo records in JSON serialisation
Address issue with embedded hasMany creation

Fixes #633. This ensures that when creating a new
record in an embedded hasMany relationship, either
via `post.get('comments').createRecord` or via
`Comment.createRecord({ post: post })`, both the
child and parent will become dirty.

This retains the "dirty tree" semantics, which
will walk up and down the tree of embedded
relationships and mark things dirty.
Created embedded records should dirty parent

Previously, embedded records (those without IDs)
that were created via ManyArray's `createRecord`
method were not properly being saved, nor dirtying
the parent's tree.

This commit ensures that an embedded record's
parent is saved on its reference when it is
added to the many array for the first time.
