SafeConfigNode::escape(): did not work correctly for strings with ! in them

The ! sign was used as escape character and thus has to be escaped
itself. In the less strict mode this wasn't done. Shouldn't affect
SyncEvolution 0.9.1 where the code was used in strict mode for
change tracking nodes, but broke the new nonce saving.
