[lib][native][web] Stop passing password up to deleteAccount endpoint

Summary:
We stopped taking the password as input in D9236, so there's no point in using it anymore.

This diff simply stops passing the parameter up. Following diffs will update the relevant components so that they don't ask for passwords anymore.

Test Plan: Test account deletion components and make sure they still work
