Update PSU if version cannot be obtained

Currently this application will ignore a PSU if the PSU code version
cannot be obtained.

However, there are several scenarios where this could occur:
* A code update was previously attempted on the PSU, and the update
  failed.  The PSU is now in a bad state, and the update needs to be
  performed again.
* The PSU is running old code that does not support reading the code
  version.

In these scenarios performing a code update on the PSU is desired.

Enhance this application so that a PSU with an unknown code version will
be updated provided that it is the correct model.

Tested:
* Verified code update was still performed if version could not be
  obtained.
* Tested where PSU information is found at start of application
* Tested where PSU information is found from InterfacesAdded event
* Tested where PSU information is found from PropertiesChanged event
* For the complete test plan, see
