Minor refactoring.
Trying to get rid of `FMLCommonHandler.instance.getEffectiveSide` where possible, since it can apparently fail in some scenarios.
The Optional.Method annotation seems to not work in dev-env in some cases... trying to work around that to fix absence of FMP and Waila related crashes in dev-env.
Fixes for the adjusted side checks.
