[Feature Request] Update threshold date when recreating recurring task

A simple example:

testing due:2023-08-15 t:2023-08-15 rec:+1w

After pressing <LocalLeader>x, I get

x 2023-08-15 testing due:2023-08-15 t:2023-08-15
testing due:2023-08-22 t:2023-08-15 rec:+1w

I think this would be better:

x 2023-08-15 testing due:2023-08-15 t:2023-08-15
testing due:2023-08-22 t:2023-08-22 rec:+1w

That would make the behavior of this plugin more consistent with https://github.com/owenh000/todo.txt-cli-dorecur (although that has a bit more complex behavior).
