Current Behavior

Tasks can end up depending on themselves if they depend on a dummy task which ends up depending back on itself. This throws a weird error like:

 NX   Could not execute command because the task graph has a circular dependency

devkit:build --> devkit:build-base --> nx:build-base --> nx:build-base

Expected Behavior

Tasks cannot depend on themselves. No errors are thrown in those cases.
