Node try to connect to previous currency peers after switch to another currency

Duniter desktop 1.7.11 on Ubuntu 14.04. All actions made on the GUI.

Running as g1-test node since installation.
Full data reset on a g1 node to help in the forks.
Few syncs later, and few hours later, the logs says that the node try to contact g1-test and g1 peers as well !
