Language not working without PsDscRunAsCredential

[Francois-Rousseau]

If you run a Get-DscConfiguration you will get the following error if have Language in your Configuration

Get-DscConfiguration : A general error occurred that is not covered by a more specific error code.

By looking in the event viewer, I found error 4252 :
Job {1DC9B5A1-DB8C-11E8-A2BC-00155D512F4E} :

The Event before is :
Job {1DC9B5A1-DB8C-11E8-A2BC-00155D512F4E} :
Impersonation reverted. Thread is running under the context of NT AUTHORITY\SYSTEM.

I took a guess to add PsDscRunAsCredential with admin credentials to the configuration and now,
The resource ask me to reboot, and after the reboot on the client machine, the Get-DscConfiguration is running perfectly :

ConfigurationName : ConfigurationNoyau
DependsOn : {[LanguagePack]fr-CA::[DSQ_BASE_NOYAU]Noyau}
ModuleName : LanguageDsc
ModuleVersion : 1.0.0.0
PsDscRunAsCredential :
ResourceId : [Language]ConfigureLanguage::[DSQ_BASE_NOYAU]Noyau
SourceInfo :
AddInputLanguages :
CopyNewUser :
CopySystem :
CurrentInstalledLanguages : {MSFT_KeyValuePair (key = "en-CA"), MSFT_KeyValuePair (key = "fr-CA")}
IsSingleInstance : Yes
LocationID : 39
MUIFallbackLanguage :
MUILanguage : en-US
RemoveInputLanguages :
SystemLocale : fr-CA
UserLocale : fr-CA
PSComputerName :
CimClassName : MSFT_Language

After that, I found that If a user is loggued, a reboot is initiated each time, same as Issue #5 .
