Restore functionality panics: close of closed channel (0.9.5-nightly)

[simcap]

Retrying a restore (after a fix done for #4671 ). It is still not working though with a different error.

My configuration is:

• 1 fresh install of a single InfluxDB instance version 0.9.5-nightly-905437c
• and therefore no clustering

With a backup snapshot I have handy (done successfully) i run this command (with no InfluxDb process running):

sudo /opt/influxdb/influxd restore -config /etc/opt/influxdb/influxdb.conf /tmp/latest-snapshot

I get the following stacktrace:
