Changed module dependency from 'account_analytic_plans' to 'account_analytic_compassion
My bad... the module should not be dependent for the production or it would install the analytic plans over the already existing data. However in a test environment, we should not forget to install first the module 'account_analytic_compassion' before installing 'sponsorship_compassion'.
