cnquery does not fetch providers based on connection

[czunker]

Describe the bug
Running this results in the help message:

cnquery run container registry gcr.io/mondoo-dev-262313/ubuntu -c "asset{ name platform ids kind runtime title }"
Run an MQL query on the CLI and displays its results.

Usage:
  cnquery run [command]

Available Commands:
  arista           Run a query with Arista EOS
...

I did not have the os provider installed, which this connection is part of.

When I manually add the os provider, all is fine again.

The same happens, when using the local connection.

To Reproduce
Steps to reproduce the behavior:

1. Remove local os proivder
2. Run above command
3. Note the help message

Expected behavior
I'd expect cnquery to automatically load the needed provider.

Should be fixed by #1668. Needs. a re-test.

No, still get the same result:

cnquery run container registry gcr.io/mondoo-dev-262313/ubuntu -c "asset{ name platform ids kind runtime title }"                           ✔ │ 06:47:39 
Run an MQL query on the CLI and displays its results.

Usage:

Fixed now:

cnquery run container registry gcr.io/mondoo-dev-262313/ubuntu -c "asset{ name platform ids kind runtime title }"                            ✔ │ 11:17:12
