Subject: [PATCH] fix($parse): default expressions of the form `a.b` to
 `undefined`

When there is an expression of the form `a.b` and there is a recursion that
specifies where the value should be placed, then when `a == null` then set
the value of the returned identifier to `undefined`

Closes #11959
