SPMI: Fix recGetStaticFieldCurrentClass (#83843)

getStaticFieldCurrentClass has very different behavior depending on
whether pIsSpeculative is passed or not, and we need to record the
resulting class handle in both cases.

This fixes a case of replays not working after recording that I hit
while tracking down a separate issue.
