AccountsUpdate: Rename update method to replace

The update methods performs a non-atomic update. This means the existing
account with the same ID is overwritten and any concurrent updates that
have been done to that account since it was read are lost. To make this
clear and to motivate callers to use atomicUpdate instead rename the
update method to replace.

Gerrit core has no callers of this method, but we want to keep it in
case it's needed by plugins.
