[vm/compiler] Fix another missing incremental DOM update
[vm/compiler] Fix another missing incremental DOM update

Rationale:
Very similar to what was recently fixed for true branch,
but this time along the false branch. Also resets the
DOM relation in the call block, since this only dominates
true and false afterwards.

Note:
This fix unblocks the improvements to the graph checker.
