Typo in configuration key name: choises.externalsource.<FIELD>

[saschaszott]

Bug Description

There is a typo in a configuration key name in authority.cfg:

DSpace/dspace/config/modules/authority.cfg

Line 188 in 16ba4dc

choises.externalsource.dc.relation.funding = fundingAuthority

The configuration key is referenced in ItemAuthority (and two integration test classes):

DSpace/dspace-api/src/main/java/org/dspace/content/authority/ItemAuthority.java

Line 57 in 16ba4dc

final static String CHOICES_EXTERNALSOURCE_PREFIX = "choises.externalsource.";
