otls: descriptive parameter names that exist

Attribute Initialize's description line still pointed at the removed
single attr field (now attr1, the first tab) and Migrate's at an
input_attr that never existed, so Houdini logged "Invalid parameter
name" for both on load. Metadata only, same versions.
