Ticket 47379 - DNA plugin failed to fetch replication agreement

Description : Schema file 10dna-plugin.ldif modified in the commit
3e2262e1c0410bdf4f9b9211aef13deb28f174d1 had a tab which should
be white spaces.  It made the schema parsing fail and the server
uninstallable.  This patch replaces the tab with white spaces.
