It's not up to you to combine the two trips and apply for a single visa for both, what you are supposed to do is to apply for a visa for the first trip from the Dutch consulate and, after your return, go through the French consulate to get another visa for the second trip. As a UK resident, it's also possible that the Dutch consulate would give you a multiple-entry visa anyway. In that case, you could use that visa for the second trip as well.
Technically however, applying to the wrong consulate should not attract a refusal (i.e. a negative decision) but the consulate should decline to process your application and refund the application fee. You might also get lucky and get a multiple-entry visa from the French consulate but the rules are clear and your application does not follow them.
