resetyubi.bat does not properly recognize failed reset

[JanMosigItemis]

Actual Behavior
Even if gpg-connect-agent runs into errors while executing the reset script, the resetyubi.bat script reports success, probably due to gpg-connect-agent not handling the errorlevel correctly.

Expected Behavior
Recognize error and stop script. Return errorlevel 1
