initial_sync_invalid_index_spec.js expects an invalid index specification option to cause members performing initial sync to abort on application. Currently the timeout is 60 seconds which is not sufficient for the initsync-3dot2-rhel-62 evergreen variant (as reported by BF-3671). We should increase the timeout to at least 120 seconds (if not the default of 5 minutes).

Additionally the initsync-3dot2-rhel-62 evergreen variant abort is triggered by a different assertion than the normal path. Add handling to recognize this assertion.
