Typescript not parsed correctly with string keys

[richardolsson]

Description

The TypeScript parser does not correctly handle string keys in the messageIds objects.

Steps to reproduce

1. Go to https://lyra.zetkin.org
2. Choose German (or any language)
3. Navigate to the strings in the feat.canvass.households.colorPicker scope

Expected Behaviour

The keys from the code (which are strings starting with #) should be listed as part of the keys, or at least be handled somehow.

Actual Behaviour

The keys are listed as undefined.

Screenshots (if you have any)

can you confirm that zetkin/app.zetkin.org#3133 actually resolved this? @richardolsson
