Add to wiki trouble shooting when StartObserver does not work fine

[nard-tech]

According to the following code, StartObserver starts only if the connection to the DB is established.

okuribito_rails/lib/okuribito_rails/railtie.rb

Lines 5 to 7 in 0b0ad03

	config.after_initialize do
	StartObserver.new.start if ActiveRecord::Base.connected?
	end

In my local environment, sometimes the connection to the DB is established after callbacks in after_initialize run.

In this case, to solve this problem, executing the following code in rails c works well.

OkuribitoRails::StartObserver.new.start
