Cleanup: Use new helpers for passing IDs from drag & drop to operators

There are now some generalized helpers for passing IDs from drag & drop
to operators via operator properties, mostly introduced in 917c096be6b9
and 8f79fa9c6780. These can be used in a bunch of places to reduce
duplicated code and explicitly share a common solution.

Side-effect: The "Name" property won't show up in the Adjust Last
Operation anymore, and its value won't be remembered over multiple
executions of the operator. Both were not at all useful from what I can
tell, and I doubt this was done intentionally.
