Bug: SQL User error on GetDB in transitional state

[WilliamMortlMicrosoft]

Closes #905

Describe the bug
If you deploy a RG, SQLServer, SQLDatabase, SQLFirewall, SQLUser at the same time you will see uncaught errors in the SQL User (and SQL Db) operator.

2020-04-08T18:30:21.485-0600	ERROR	controller-runtime.controller	Reconciler error	{"controller": "azuresqluser", "request": "default/sqluser1", "error": "1 error occurred:\n\t* sql.DatabasesClient#Get: Failure responding to request: StatusCode=404 -- Original Error: json: cannot unmarshal array into Go struct field serviceError2.details of type map[string]interface {}\n\n"}

To Reproduce
put the manifests in a directory and run kubectl create -f <directory>...you won't see the errors until just before everything finishes...

everything comes up eventually but these errors should still be caught

Expected behavior
no stack traces in logs

Fix
Updated Azure SQL
