Existing device MEG5113-0300/MEG5165-0000 has new endpoint id

[Moony83]

While adding a couple of Merten wiser Shutter controls, herdsman ran into a Type Error: "TypeError: Cannot read property 'bind' of undefined".
When examining the paring process with herdsman on debug, it seems that the endpoint id is 21 instead of 1.
(See https://pastebin.com/pdUMskcp)

devices.js has this model currently configured with "const endpoint1 = device.getEndpoint(1);"
I suggest mending devices.js and including a potential endpoint id of "21"

Does const endpoint1 = device.getEndpoint(1) || device.getEndpoint(21); fix it?

Actually i was a bit wrong there, it seems like Endpoint 5 is the one to go. At least partly.
I managed to integrate with const endpoint1 = device.getEndpoint(1) || device.getEndpoint(5);

The device(s) now show up correctly on MQTT and report their linkstate and position.
However, the logfile still notes a couple of "no converter" lines:

Thanks, fixed the code.

These no converter messages are normal (it just indicates these won't be converter to MQTT, because these messages are not interesting).

Changes will be available in the latest dev branch in a few hours (https://www.zigbee2mqtt.io/how_tos/how-to-switch-to-dev-branch.html)
