Fix flowlog crash (#157)

Issue #, if available: [#1931](aws-controllers-k8s/community#1931)

Description of changes:
While creating FlowLog, if logDestnation does not exist then CreateFlowLogsWithContext does not return the error. However, Unsuccessful field in the response is set. FlowLog is not created in aws. Due to this, controller crashes while accessing the flow log id from the response (resp.FlowLogIds[0]).
Fixing the issue by checking if FlowLogIds has valid length before accessing it.
