Cli: Remove setting default value for Setting not used by the CLI

[pedr]

Summary

In the Desktop: Performance: Faster startup and smaller application size it was introduced a new constant pluginAssetDir, which seems to be causing some issue with the desktop configure, like related in the parent issue.

While trying to find a solution, I didn't find a reason why the constant needed to be set on app-cli as doesn't seems to be used anywhere there since we don't support the HTML exporter there and neither plugins.

Testing

To test the change I run all automated tests and made some manual ones like:

Test 1

1. Remove the ~/.config/joplindev directory
2. Starting the app-cli application
3. Create notebook, note, edit note, etc.

Test 2

1. Remove the ~/.config/joplindev directory
2. Starting the app-cli application
3. Create notebook, note, edit note, etc.
4. Export the note to md, jex and raw format

Thank you for working on this!

it was introduced a new constant pluginAssetDir, which seems to be causing some issue with the desktop configure, like related in the parent issue.

#12545 includes an "about" section with information about the desktop app. This section marks the app as based on 24df674, which does not include 86ee95a as a parent commit. Since it wasn't included in this version of the application, I don't think the pluginAssetDir change could have caused the linked issue (though it could have caused a similar issue in later versions of the app :) ).

Cli: Fixes #12545:

For issue tracking purposes, I would suggest removing "Fixes #12545" from the title and summary, as this change should not affect the desktop app.
