Speed up mxs1713_lots_of_databases

Browse Source 
The SHOW DATABASES greatly slows down the test. By doing that only from
time to time, the test time drops from roughly 160 seconds to 15
seconds. There's also no point in continuing the test after a failure has
been seen.

Also added a missing sync_slaves to the database creation to make sure
they are created on all servers before the test starts.
