#### SUMMARY
<!--- Explain the problem briefly below -->
Installing `amazon.aws` collection fails on ansible/ansible@devel, supposedly because of the embedded symlinks:
```console
ERROR! Unexpected Exception, this is probably a bug: "filename 'tests/unit/mod
ules/placebo_recordings/aws_direct_connect_link_aggregation_group/nonexistent_
lag_status' not found"
```

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
<!--- Write the short name of the module, plugin, task or feature below, use your best guess if unsure -->
ansible-galaxy CLI

##### ANSIBLE VERSION
