Revert "Minidump/Windows: Fix module lookup"

Although there is nothing wrong with this patch, the test added here
uncovers a problem in other parts of the code which cause the test to
fail when running under asan. Reverting the patch until I can fix the
underlying issue(s).

This reverts commit r368416.
