[qa] Wait for specific block announcement in p2p-compactblocks
Change check_announcement_of_new_block() to wait specifically for the
announcement of the newly created block, instead of waiting for any
announcement at all. A difficult to reproduce failure in
check_announcement_of_new_block() that happened in a travis build
(https://travis-ci.org/bitcoin/bitcoin/jobs/175198367) might have happened
because an older announcement was mistaken for the expected one. The error
looked like:
Assertion failed: Failed
File ".../bitcoin/qa/rpc-tests/test_framework/test_framework.py", line 145, in main
self.run_test()
File ".../bitcoin/build/../qa/rpc-tests/p2p-compactblocks.py", line 787, in run_test

assert(predicate(peer))
This commit also changes the assertion failed message above to include more
detailed information for debug.
