[wintest] tests not executed

[Stefan Leichter]

Hello,

since this week i get a lot more messages "Can't parse subtest output of .." 
when runnning winetest-latest.exe.

The reason seems to be that the test executables with only one test target 
(e.g advapi32_test.exe) do not longer list its targets when started without 
target. Now the single target is performed.

What is the reason for this change ?

Bye Stefan
