test: fix catchup loop in outbound eviction functional test

Browse Source 
The catchup loop in the outbound eviction functional test currently has
a small flaw, as the contained waiting for a `getheaders` message just
waits for any such message instead of one with the intended block hash.
The reason is that the `prev_prev_hash` variable is set incorrectly,
since the `tip_header` instance is not updated and its field `.hash` is
None. Fix that by updating `tip_header` and use the correct field -- we
want the tip header's previous hash (`.hashPrevBlock`).
