Lint/UnreachableLoop false positive when using conditional next

[Tao-Galasse]

In a loop where I conditionally return a value or calling next, rubocop triggers the Lint/UnreachableLoop.

Here is an example :

%w[foo bar tao].each do |name|
  return User.find_by(first_name: name) || next
end

If I have a user named tao but no user named foo or bar, this will run 3 times.

Expected behavior

Not raising a Lint/UnreachableLoop warning.

Actual behavior

W: Lint/UnreachableLoop: This loop will have at most one iteration.
      %w[foo bar tao].each do |name| ...

Steps to reproduce the problem

You can use the example above. You can even replace next by something like (puts 'next'; next) to see it iterate.

RuboCop version

1.13.0
