Ensure that apis are unhidden even if there is no vdex

We were relying on the vdex to unhide apis during dequickening for
JVMTI. This meant that hiddenapi flags could get through if there is
no vdex file. We fixed this by making sure to get rid of hiddenapi
flags even without vdex.

Test: ./test/run-test --dev --host --interpreter 674-hiddenapi;
      # Examine output for slicer crashes.
