config.sys_language_overlay = hideNonTranslated is ignored

[tomasnorre]

The behaviour is same with sys_language_overlay = 1 and
sys_language_overlay = hideNonTranslated.
The the non-translated elements of the default language are rendered.

-- Comment from forge:
I can confirm the problem. Translation falls back into default language, even if it's not in fallback order.

The changes in patch seem to work, but the line numbers differ from line numbers in (latest) version 0.8.4.

-- Comment from forge:
I found another workaround (see attached patch):

if ($row['uid'] == 0 && $row['pid'] == 0) {
$row = NULL;
}
added at the beginning of getRecordOverlay_postProcess will return early and does not cause problems with getRecordOverlay in t3lib_page since $row has to be an array with uid and pid keys after the getRecordOverlay_preProcess invocation.
