Unable to build an app in a directory that has a tasks.cr file

[jwoertink]

Right now we assume that if there's a tasks.cr file, then you must be inside a Lucky app directory

lucky_cli/src/lucky.cr

Line 14 in ccaa571

inside_app_directory = File.file?(tasks_file)

Then when you run lucky -h you'll get different output depending... This is helpful to avoid an issue where you generate a Lucky app inside of a Lucky app accidentally...

However, Breeze has a tasks.cr file, and is not a Lucky app... so when trying to run the integration specs https://github.com/luckyframework/breeze/blob/674b438fde9da5686a49c9e35290365e45bf9f85/spec/integration_spec.cr#L11 it attempts to build a Lucky app inside of the root of the breeze directory, and instead of just saying "nope", you get

❯ lucky init.custom test-project

In lib/avram/src/avram/database.cr:156:5

 156 | settings.credentials
       ^-------
Error: undefined local variable or method 'settings' for Avram::Database+.class

which really makes no sense... Moving this to a tmp/ dir "solves" it...

I do like having the safety of not accidentally generating an app inside an existing app, but I guess is it really necessary vs what we lose not being able to?
