Description

In a managed schema containing just a single dynamic copy field directive - i.e. a glob source or destination - deleting the copy field directive fails. For example, the default configset (data_driven_schema_configs) has such a schema: the *->_text_ copy field directive is the only one.

To reproduce:

bin/solr start -c
bin/solr create my_solr_coll
curl "http://localhost:8983/solr/my_solr_coll/schema" -d'{"delete-copy-field":{"source":"*", "dest":"_text_"}}'

The deletion fails, and an NPE is logged:
