Get-AzAutomationAccount has inconsistent/unreliable output

### Description

Get-AzAutomationAccount has inconsistent/unreliable output. It's a bit the same as is experienced with the get-AzResource cmdlet.

Out of running Get-AzAutomationAccount 10 times I get 4 times my automation account back, 6 times not.

Reproduce the issue by running Get-AzAutomationAccount repeatedly and compare the results with the successful and empty responses shown. Start at the GetAzureAutomationAccount entry point and inspect the request to the Microsoft.Automation automationAccounts endpoint. Done means the cmdlet reliably returns the automation account instead of silently producing no output.
