Dont remove logs from failed deployments if is included by Minimum to keep

Summary

Failed logs can be extremely important as the logs for a successful deployment. Bamboo seems to expire these currently even when a deployment falls under "Minimum Deployments To Keep".

Environment

Bamboo 5.12.X
Bamboo 5.9.X

Steps to Reproduce

1. Set the global expiration settings to:
Expire After: 0 days
Min builds to keep: 3
Min deployments to keep: 3
2. Run a few deployments, then for the last 3 have one fail and 1 sucessful.
3. Manually run Expiraiton.

Expected Results

Most customers would expect that all logs should be preserved as the deployments have been preserved.

Actual Results

Deployments beyond the minimal 3 are correctly deleted. However, the logs for the failed builds are cleared - but the successful build is kept.

Workaround

Not ideal, but extend the value for Expire After the logs for longer.
