Mismatched entity and/or field definitions after applying duration_field_update_8201

Thank you for reporting this bug.

Which version of Duration field did you upgrade from?

I will take a look at the problem.

From 8.x-2.1.

Possibly not related specifically to the issue of updating the schema properly, but also upgrading from 2.1 and running 8201 update throws error because it attempts to update non existing tables (in my case, commerce_product__revision__field_duration).

Here's a patch for 2.2 while the whole issue is being looked at, which checks if the table is there before hand.
