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.
Motivation for this change is mainly to make sync_blocks behavior easier to
understand. Behavior is unchanged in the normal case when there are only 2
nodes in the rpc_connections set. When there are more than 2 nodes, the
previous "timeout -= wait" statement wouldn't take into account time spent
waiting for all nodes and as a result could lead to blocking for longer than
the requested timeout.
Instead of syncing to max height returned by the waitforblockheight RPC, sync
to the max height returned by the getblockcount RPC.
This change was suggested by Suhas Daftuar <sdaftuar@chaincode.com>.
