Set WarningsReturnAsErrors = 0 before connection

[obelisk-services]

Description

We have moved sqlsrv_configure('WarningsReturnAsErrors', 0); prior to sqlsrv_connect($this->hostname, $connection) because if there is a warning or an information message establishing the connection, it will treat it as an error and Codeigniter will throw an exception. Driver's configuration should be set prior the connection.

Example:
Before change, exception shows up (image1): "Unable to connect to the database. Main connection [SQLSRV]: Driver's SQLSetConnectAttr failed", but it is thrown by information message (IM006), as we can see when executing sqlsrv_errors() (image2).

After change: Connection is established without problems:
