Mark behavior of QFileInfo::absoluteFilePath as undefined in corner cases

Browse Source 
The current description was misleading, since e.g.

QFileInfo().absoluteFilePath()

will always return an empty string.

QFileInfo("").absoluteFilePath()

however will return the current working directory ...

Instead of documenting these small quirks we should rather mark the
exact behavior as undefined, like we already do for absolutePath().
