Chained notifies don't work when the notifies are defined in different recipes

[pocke]

Chained notifies don't work when they are defined in different recipes.
For example:

# a.rb
execute '1' do
  command 'true'
  notifies :run, 'execute[2]'
end

# b.rb
execute '2' do
  action :nothing
  command 'true'
  notifies :run, 'execute[3]'
end

execute '3' do
  action :nothing
  command 'true'
end

With these recipes, I expect itamae executes 1, 2, and 3.
But I got an unexpected result, which depends on file order.

# It is the expected result.
# 1, 2, and 3 are executed.

$ RUBYLIB=./lib bin/itamae local a.rb b.rb

# It is unexpected behavior.
# 1 and 2 are executed, and 3 is enqueued,
# but 3 is not executed.
