Henrik Jonsson 023da9c36b prometheus: Fix channel_id name and prevent crashing
With c-lightning v0.7.0, there seems to be no `short_channel_id`
key present in the input sent to the `prometheus.py` script when
it is is called via the `plugin` config value for c-lightning
when a channel is opened.

Without this change, the script throws `500 Internal Server` error
when doing `$ lightning-cli fundchannel <id> <sats>`.

A sample JSON messages passed to the plugin is:
