Installing adapter doesn't work

[patrickbs96]

Describe the bug
I wanted to add the Twinkly adapter to the discoverable adapters but by trying to install the adapter I ended up with an empty instance. As I thought there might be an error with my added code I tried to install different adapters but with the same result. The Admin view is not even available as if the adapter wasn't installed properly.
If I deinstall the broken adapter and reinstall it manually it works.

To Reproduce
Steps to reproduce the behavior:

1. Discover adapters
2. Check instance with keyword "new" in description
3. install
4. See error

Expected behavior
Working instance of the adapter.
