modules/performance: ensure all lua dependencies are byte-compiled

This commit replaces custom lua plugins in tests with shared stub
plugins from utils module.
After this change the test has started to fail. Debugging this issue
I found out that dependencies of plugins weren't processed.
This commit improves the test assertion to detect duplicated
dependencies in this case and fixes the underlying issue by also
processing dependencies.
