change verbose mode default to true and change param accordingly

vebose mode maps to uncompressed hierarchy on device. since we
are using uncompressed hierarchy by default for device test,
we should use verbose mode by default here.

otherwise when user uses viewer tool, it will show compressed
hierarchy by default, which causes test cases to be written
against wrong assumptions

since we are changing the heuristics here, we are also changing
'--verbose' to '--compressed' accordingly
