batchiepatchie backend crashes when new job spins up

[erhaben-Raupe]

We have batchie patchie running in a production setup. Whenever new job spins up backend throws nil pointer reference and crashes.

{"level":"info","msg":"Logging ECS cluster statuses.","time":"2023-01-19T11:25:36Z"}
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0xa54007]

goroutine 11 [running]:
github.com/AdRoll/batchiepatchie/jobs.MonitorECSClusters({0x7f192019aff8, 0xc000012c60}, {0x160a640, 0x0, 0x1?})

This happens when the job status is STARTING in AWS console. When the status change to RUNNING I can restart batchiepatchie again.

FYI, my setup is running on ubuntu 22.04 in an EC2 and the capacity provider for batch is Fargate
