[PATCH 2/2] sapi: Improve GetDefaultTokenId stub.

This patchset is a first step towards fixing https://bugs.winehq.org/show_bug.cgi?id=49641

My previous attempt (https://www.winehq.org/pipermail/wine-devel/2020-August/171124.html)
was a rather large patch and had tests that I believe were much too invasive (deleting and
restoring system registry keys).

Since my previous attempt was dropped (fair enough), in order to reduce the patch review burden,
this patch is much smaller and is only meant to cover the bug's use case.
