Let RemoteInputView call setTextOperationUser() only once

This is a small follow up to my previous CL [1], which made
RemoteInputView call TextView#setTextOperationUser() so that the text
operation uesr ID can be determined by the notification user ID.

Since the relationship between NotificationEntry and RemoteInputView
is immutable, there is no need to call setTextOperationUser(null) to
reset the target user ID in RemoteInputView#reset(), which may have
some race conditions.

With this CL, RemoteInputView calls setTextOperationUser() only once
immediatelly after inflation.
