BUG/MINOR: peers: Missing TX cache entries reset.

Browse Source 
The TX part of a cache for a dictionary is made of an reserved array of ebtree nodes
which are pointers to dictionary entries. So when we flush the TX part of such a
cache, we must not only remove these nodes to dictionary entries from their ebtree.
We must also reset their values. Furthermore, the LRU key and the last lookup
result must also be reset.
