sqlalchemy: Query.get() in dictionary mode does not respect orm.synonym()

Describe the bug

When using a dictionary for specifying primary keys in Query.get(), synonyms for the primary key fields are not being respected.

To Reproduce

from sqlalchemy import create_engine
from sqlalchemy.orm import Session, declarative_base, synonym
from sqlalchemy.schema import Column, ForeignKey
from sqlalchemy.types import Integer

engine = create_engine("sqlite:///:memory:")
session = Session(engine)
Base = declarative_base()

class Parent(Base):
    __tablename__ = 'membership'
    child_id = Column(ForeignKey('child.id'), primary_key=True)
    synonym_child_id = synonym(child_id)


class Child(Base):
    __tablename__ = 'child'
    id = Column(Integer, primary_key=True)

Base.metadata.create_all(engine)

session.query(Parent).get({
    'synonym_child_id': 0,
})

Error

The above exception was the direct cause of the following exception:
