Merge branch 'js/fsmonitor-refresh-after-discarding-index'

The fsmonitor interface got out of sync after the in-core index
file gets discarded, which has been corrected.

* js/fsmonitor-refresh-after-discarding-index:
  fsmonitor: force a refresh after the index was discarded
  fsmonitor: demonstrate that it is not refreshed after discard_index()
