MIFOSX-1060: Holidays declared for head office is not getting applied to the newly attached child offices

Migrated over from MifosForge at https://mifosforge.jira.com/browse/MIFOSX-1060

Original description:

1.Create holiday under Head office and activate it.
2. Create a child office under that head office.
3. Click on the Administration -> Organization -> Manage Holidays - in which select the above created child office from the dropdown, - no holidays are displaying under that office.

Ideally if in the organization level (or head office) any holiday is declared then it should affect the child offices which are attached newly even after declaring the holiday.
