Updating name resets Space dropdown

[TheophileMot]

Great app! Small bug: when you click "Update name", the dropdown with the index of the Space resets to 1.

So, for example, if you're changing the name for Space 2, and you click "Update name" twice in a row, then you will have changed both Space 2 and Space 1 to the same name.
