Comment 5 for bug 1937173

To be clear a bunch of the warnings are intentional e.g. on the try to load breezy.testingplugins.some_error

But I tried to reduce the variables:

test_plugins_with_the_same_name_are_not_loaded was failing when run combined.

Overall we have:
test_plugins.TestLoadingPlugins.test_plugin_with_bad_api_version_reports
test_plugins.TestLoadingPlugins.test_plugin_with_bad_name_does_not_load
test_plugins.TestLoadingPlugins.test_plugin_with_error
test_plugins.TestLoadingPlugins.test_plugin_with_error_suppress
test_plugins.TestLoadingPlugins.test_plugins_can_load_from_directory_with_trailing_slash
test_plugins.TestLoadingPlugins.test_plugins_from_different_dirs_can_demand_load
test_plugins.TestLoadingPlugins.test_plugins_with_the_same_name_are_not_loaded

Let us see which few are enough to make it fail.

It seems if either of:
- test_plugins_from_different_dirs_can_demand_load
- test_plugin_with_error
are enabled, then a few fails.

But these combinations are complex I need some more runs.
I want a combination of just two for debugging.
