Reactor is checking during update user when password is not being changed

Description

We are checking for a password breach during a user change even when a password is not provided. This means we get a validation error from reactor and we create an event log.

There is no functional problem for the end user, it is just noise in the event log.

Expected behavior

Do not check unless we have a password during the user update so we don't spam the event log.
