Getting AadAuthOperationCannotBePerformedWhenServerIsNotAccessible on ARM template when deploying server admin with dependsOn for server

Hello, I am intermittently seeing this error when deploying a resource of type `Microsoft.DBforPostgreSQL/flexibleServers/administrators` via ARM template.

_StatusCode: Conflict, Status: Failed, ErrorCode: AadAuthOperationCannotBePerformedWhenServerIsNotAccessible, ErrorMessage: The server '{server name}' is not in an accessible state to perform Azure AD Principal operation. Please make sure the server is accessible before executing Azure AD Principal operations._

I first deploy a postgres server (`Microsoft.DBforPostgreSQL/flexibleServers`) and explicitly depend on this server for the deployment of the `Microsoft.DBforPostgreSQL/flexibleServers/administrators` resource.

This situation complicates having stable, reliable deployments as sometimes the `dependsOn` condition is satisfied when apparently the postgres server is not ready for an Azure AD operation. I think this is a bug, the `dependsOn` condition for the postgres server should not be fulfilled until the server is ready for an Azure AD operation.

example arm operation id: A6CE82DD8683DCEF, sadly don't have the correlation id available
