Commands module is causing errors for missing help languages

Looks like we need to use -ErrorAction Ignore on the Import-LocalizedData call here:

https://github.com/PowerShell/PowerShellEditorServices/blob/master/module/PowerShellEditorServices/Commands/PowerShellEditorServices.Commands.psm1#L1

Ideally we'd see the errors in case there's a legitimate problem but for now the logs are getting filled with this error (probably because of another issue in PowerShellContext) so it's better to cut down on the noise.
