CPP-43482: Disable ctest plugin in qodana-cpp

[bindreams]

The issue mentioned in MR title reproduces often on qodana-cpp. Dmitry Kozhevnikov suggested:

As a simple workaround which should make the issue go away but won't fix the underlying issue - you can disable org.jetbrains.plugins.clion.ctest plugin (it's worth doing anyway, you don't need it on Qodana run).

P.S. Please let me know if I should have added the plugin to disabled_plugins or removed it from included_plugins. I am not sure what the difference is.
