MeHR fails when reservable service is not active

[dneise]

In order to get service IDs for the daily reservations/getAll request we do services/getAll and select only the reservable ones.

However, we noticed with one Hotel, that created a reservable service, which was later deleted (I assume service deletion via the MEWS commander, results in services being set to isActive=False) that MeHR crashed since the reservations/getAll returned with:

{'Message': 'Invalid ServiceIds.', 'Details': None}

which was not correctly handled.

Proposed fixes include:

• let the user configure the Service via the config.json (Con: less convenient)
• keep serviceID auto detection, based on "reservable" and add requirement isActive=True
• when multiple serviceId are detected, execute individual reservations/getAll calls for each individual serviceId and concatenate the results. This should make MeHR more robust in cases where for some reason the call fails for a certain serviceId.
