Koha::Plugins::InstallPlugins()
For each plugin module found, it will test that the plugin can be loaded,
and if it can, will store its available methods in the plugin_methods table.
+NOTE: We re-load all plugins here as a protective measure in case someone
+has removed a plugin directly from the system without using the UI
