FSI: Set ramping defaults to false (#1231)

* FSI: Set ramping defaults to false

Since we are moving to split meshes as the current strategy setting
ramping defaults to `False`.

I have been investigating why the temporal ramping is causing
simulations to fail since the bug fixes regarding hub motion, and I
can't find any issues with it at the moment. So it seems best to keep
that turned off as well.

* Update real defaults
