Added switch that let us 'un-stub' certain dbus clients.

per gtest.h, the expected value should come first. the right order gives you a
better error message. please fix other places too.

Done.

I'm confused. Why can "CrosDisks" be parsed, where as the string in the mapping
table is "cros_disks"?

GetDBusClientType() does case-insensitive matching but doesn't seem to ignore
'_'.

Yeah, this test should not pass :). Fixed.
