this is for testing a non-in-use update, correct? please assert that 'opv' and
'cmd' are not present in the registry (these two values are present when an
in-use update is applied). i think this is true for the BINARIES subkey as well;
please check the code (or try it out) to be sure.

In-use update:
 CHROME subkey: pv, opv, cmd exist
 BINARIES subkey: pv, opv exist
 LAUNCHER subkey: pv exists
Non-in-use update:
 CHROME subkey: pv exists
 BINARIES subkey: pv exists
 LAUNCHER subkey: pv exists

I modified the test to verify that opv and cmd don't exist for the CHROME and
BINARIES subkeys. Maybe verifying that cmd doesn't exist for the BINARIES subkey
is overkill, but it's not invalid and could catch regressions.
