Too many warnings logged for total order commands

RetryPrepareException is harmless, on the same level as OutdatedTopologyException, so it should be logged at debug level instead of warning.

Tx commands received before the initial topology also result in a NullPointerException that is logged at the error level, because they try to access the transaction table before it finished initializing. Non-TO tx commands avoid this by calling isCommandSentBeforeFirstTopology(commandTopologyId), TO tx commands can do the same.
