I don't think Rumple had any doubts about Emma. All the way back in the Pilot, when Snow and David go to see him in the Jail, Rumple points out that it will be the Charming Daughter that will break the curse. And every action taken by Rumple prior to the curse was based on the fact that Emma is the savior, including insuring that Snow and David actually get together.

That still leaves the question of what his plans for Alexandra were.
