Revert "[PWD Editing Android] Save changes through PasswordEditingDelegateProvider"

This reverts commit 6c35d28d.

Reason for revert: 
If there's multiple credentials in the password list and one is edited, the rest of the credentials disappear and only the one that was edited stays in the list. That shouldn't be happening and needs to be corrected before landing this CL.

Original change's description:
> [PWD Editing Android] Save changes through PasswordEditingDelegateProvider
> 
> PasswordEntryEditor saves changes for a credential record when the
> Save button is clicked through PasswordEditingDelegateProvider.
