FileSystemAlreadyExists when building in CircleCI

[sargunv]

I'm getting FileSystemAlreadyExists exception from tiny-remapper when building a mod (sargunv/always-drop-loot) in CircleCI. From discussion in FabricMC/tiny-remapper#7, it sounds like loom is not releasing a file. Could be related to #45.

I can reproduce the issue every time I build in the CircleCI environment. Perhaps building inside a docker container from their image (circleci/openjdk:8-jdk) would reproduce it.

Here's a sample stack trace of the crash from tiny-remapper: https://pastebin.com/5MjxLqfd

Closing this as ive not seen issues with this for a long time. if its still an issue please re-open a new one.
