Setting Custom provider as preferred doesn't work

Describe the bug Setting custom provider as preferred doesn’t seem to work.

Code To Reproduce

from eodag import setup_logging
from eodag.api.core import EODataAccessGateway

if __name__ == "__main__":
    # Create an EODAG custom STAC provider
    setup_logging(verbose=3)
    dag = EODataAccessGateway()

    # Add the custom STAC provider + output + login an password
    outputs_prefix = r"D:\capella_eodag"

    dag.update_providers_config("""
    capella_provider:
        search:
            type: StaticStacSearch
            api_endpoint: https://capella-open-data.s3.us-west-2.amazonaws.com/stac/capella-open-data-by-product-type/capella-open-data-slc/collection.json
        products:
            GENERIC_PRODUCT_TYPE:
                productType: '{productType}'
        download:
            type: AwsDownload
            flatten_top_dirs: True
            outputs_prefix: %s
    """ % (outputs_prefix))

    # Set the custom STAC provider as preferred
    dag.set_preferred_provider("capella_provider")
    print(dag.get_preferred_provider())

Output

Environment:

• Python version: Python 3.9.13
• EODAG version: eodag (Earth Observation Data Access Gateway): version 2.7.0

Additional context

The custom provider comes from #519

Can you try to install v2.7.0 in a new virtual environment, and to use a new empty configuration file (instead of your ~/.config/eodag/eodag.yml) ? This may help us to identify what causes this issue.

I also tried your example on windows, and got capella_provider as preferred provider as expected…

I tried to add one lib at a time, and it seems to fail when adding eodag-sentinelsat but I don’t know why 😰
