Bug 10602: Set default value for authority fields via the framework

This patch allows to define default values in the authorities framework.

Some code already existed but the feature did not work.

Test plan:
1/ Choose a framework, field and subfields.
2/ Define a default value.
3/ Create a new authority and check that the subfield is
automatically filled with the default value.
