init.toml does not take effect immediately
<!-- bug reporting without issue template will be closed automatically -->

## Expected behavior

I changed init.toml, commentd custom_plugins.
```
[[custom_plugins]]
  name = 'Tokubara/neoterm'
```
Then I restarted spacevim, the plugin is still in effect.
After 20 minutes(while I keeped restarting spacevim), the plugin was not loaded anymore.
Then I uncommented and reopened spacevim, the plugin was still not loaded. What can I do to make the plugin work?
```
[[custom_plugins]]
  name = 'Tokubara/neoterm'
```
