Computer rename with domain join fails when computer object exists in AD prior to join.

[slyckstyx]

Repro steps: Create computer object in AD with target computer name (preseeded computer object). Attempt to use xComputerManagement module MSFT_xComputer resource to join the domain and rename to target computer name. The resource will join the computer to the domain, but the rename fails, as the computer object already exists in AD.

To fix: Need to rename the computer object before joining to domain.
