Cannot deploy a k8s bundle which contain local charms that need resources

Hello,

I found an issue deploying a k8s bundle through libjuju that is causing two problems:

When a charm is pointing to the charm store, even if a resource is override in the bundle, libjuju tries to get the information of the resource from the charm store.
When I point to a local charm, it tries to get the resource from the charm store and it will fail with a 404 not found url.

This is the bundle I have been testing with:

description: Squid Bundle
bundle: kubernetes
applications:
  squid-libjuju:
    charm: ./squid
    scale: 1
    resources:
      image: sameersbn/squid:3.5.27-1

The charm can be downloaded executing this command:

charm pull cs:~charmed-osm/squid-0

Script used for the testing:

from juju import loop
from juju.model import Model

async def main():
    model = Model()
    print('Connecting to model')
    # Connect to current model with current user, per Juju CLI
    await model.connect()

    try:
        print('Deploying bundle')
        applications = await model.deploy(
            './k8s-bundle',
        )

        print('Waiting for active')
        await model.block_until(
            lambda: all(unit.workload_status == 'active'
                        for application in applications for unit in application.units))
        print("Successfully deployed!")
        print('Removing bundle')
        for application in applications:
            await application.remove()
    finally:
        print('Disconnecting from model')
        await model.disconnect()
        print("Success")

if __name__ == '__main__':
    loop.run(main())

Error when deploying it with libjuju:
