How reproducible:
always

Steps to Reproduce:
1. Create product, repo (zoo), promote it to Dev environment, sync the repo.
2. Create content definition, add  filter to it and add Package Group Excludes rule to exclude "birds" group from Dev environment.
3.Publish the content definition and promote content view to Dev environment.
4. Create activation key by adding content view into it.
5. Register a client by activation key, subscribe to zoo pool.
6. Try to install "birds" group on system by CLI command "system packages --install_groups birds --org --name". It will show output: "Remote action finished:No new packages installed".
7. Try to install some non existing "wrong" group on system by CLI command "system packages --install_groups wrong --org --name". Again ,it will show output: "Remote action finished:No new packages installed".

Actual results:
in any case when group name is does not exists in repo or is filtered, it's installation shows message "Remote action finished:No new packages installed".

Expected results:
it shout have output that package group is not available in environment and content view.

Additional info:
for existing group which is promoted to environment it works wine.
