stream of another module the installation fails with conflict because the default
stream is also active.

anaconda 34.25.0.23-1.el9

How reproducible:

Steps to Reproduce:
Start installation with following kickstart:
repo --name modilarity_repo --install --baseurl {TEST_REPO_URL}
%packages
# tr-modular:legacy depends on tr-dependency:10 but tr-dependency:20 is default stream
@tr-modular:legacy
%end

    Problems in request:
    Modular dependency problems with Defaults:

     Problem: module tr-modular:legacy:1:.noarch requires module(tr-dependency:10), but none of the providers can be installed
      - module tr-dependency:10:1:.noarch conflicts with module(tr-dependency) provided by tr-dependency:20:2:.noarch
      - module tr-dependency:20:2:.noarch conflicts with module(tr-dependency) provided by tr-dependency:10:1:.noarch
      - conflicting requests

    Some packages, groups or modules are broken, the installation will be aborted.

Installation finishes without problems,
@tr-modular:legacy and @tr-dependency:10 are installed
