Avoid printing lvm2 command trace, if the test finds the 'dmeventd' was started unxpectedly during testing as the last command is hardly ever responsible for this Also reorder some messages when doing teardown of devices. Do not print 'help' message from hostname command, when it does not support option '-I'.
