Not working "flipflop:xxx" rake tasks

[mateuszgorniak]

Hello! My team uses flipflop for our project and today we noticed rake tasks are not available in our app (we get Don't know how to build task 'flipflop:features' (See the list of available tasks with "rake --tasks")), everything else is working as expected. In our case it's just rather standard Rails app (with Rails 5.2.6 version used). Anyone else noticed the same problem? Seems we don't use any extra customisation that would cause such regression.
