Description
An example of a failing DynamicEmbeddedDocument:
class DynamicSettings(DynamicEmbeddedDocument):
known_field = StringField()
class Person(Document):
name = StringField()
settings = EmbeddedDocumentField(DynamicSettings)
p = Person(settings=DynamicSettings(known_field="abc", dynamic_field1="123"), name="John").save()
# The following raises a LookUpError
Person.objects(settings__dynamic_field1="123").first()

Research direction
Start by running the DynamicEmbeddedDocument example and tracing the Person.objects(settings__dynamic_field1="123") lookup path; the issue names no files or tests. Done means the query no longer raises LookUpError and returns the matching Person, with regression coverage for this example.
