BUG/MINOR: config: clear proxy->table.peers.p for disabled proxies

If a table in a disabled proxy references a peers section, the peers
name is not resolved to a pointer to a table, but since it belongs to
a union, it can later be dereferenced. Right now it seems it cannot
happen, but it definitely will after the pending changes.

It doesn't cost anything to backport this into 1.5, it will make gdb
sessions less head-scratching.
