Building mof file ignores any -ErrorAction SilentlyContinue in DSC Resources

[ThePSAdmin]

When converging in test-kitchen, it fails with the following error:

if (!$?) { if($LASTEXITCODE) { exit $LASTEXITCODE } else { exit 1 } } with id: 1DEA0CC5-2ABF-411C-A74A-BBA3FC0AD01A

After troubleshooting, I found that in this code block https://github.com/test-kitchen/kitchen-dsc/blob/master/lib/kitchen/provisioner/dsc.rb#L124

the mof file is built, but any errors that are ignored in the dsc resources causes kitchen-dsc to exit. In this case, its the following line from the build in PSDesiredStateConfiguration module:

$reg = Get-ItemProperty -path $key -name "PSDscAllowPlainTextPassword" -ea SilentlyContinue

I'm guessing the checking of the $error variable was put there for a reason, so I thought I'd check via this issue before opening a pull request. Otherwise a suggested fix is using -erroraction stop when compiling the mof and adding the exit code to the catch block.
