Verification failed with manually created plugin
Steps to reproduce:
- Compile your own Jami plugin.
- Click the "Install manually" button on Jami and try installing the plugin.
Expected: The plugin should be installed
Actual: Since the plugin store patch, every plugin installed on Jami have to contain a valid certificate, but this check should be disabled on manually installed plugins, to make it easier to develop and share small plugins without having the need to make it certified by Savoir-faire Linux.
