exists() hangs when it should return false

[snoblenet]

You'd expect this to echo true, and this is what happens:

:lua print(require('plenary.path'):new('.'):find_upwards('node_modules'):exists())

You'd expect this to echo false, but instead it just hangs:

:lua print(require('plenary.path'):new('.'):find_upwards('red_herring'):exists())
