Fatal because --exclude does not exclude for version request with --all

• Yes, I reviewed the contribution guidelines.
• Yes, more specifically, I reviewed the guidelines on how to write clear bug reports.

Describe the current, buggy behavior

wp theme update --all --exclude=foo
wp plugin update --all --exclude=foo

ParseThemeNameInput::check_optional_args_and_all (same for plugin) will try to get update info via themes_api for all themes/updates even the excluded ones.
This is a problem if the theme/plugin is excluded because it will make the updater crash e.g. if it hooks onto filter themes_api_args in the themes_api function, which leads to nothing getting updated
(since the add_filter function has a fatal error)

Describe what you would expect as the correct outcome

Don't check excluded plugins/themes for newer version/updates.

Let us know what environment you are running this on

WP CLI 2.10.0

Provide a possible solution

Change check_optional_args_and_all to skip excluded in $all case?

Hey @danielbachhuber @kkmuffme, I couldn't replicate this issue. I tried it on both a live site with WP-CLI 2.10.0 and in a Behat test. Everything seems to be working fine. It updated some plugins and skipped the one specified in the --exclude parameter. I didn't encounter any fatal errors.

A live site

Behat test

@require-wp-5.2
  Scenario: Updating all plugins with some excluded
    Given a WP install
    And I run `wp plugin install wordpress-importer --version=0.8 --force`
    And I run `wp plugin install classic-editor --version=1.0 --force`

    When I try `wp plugin update --all --exclude=wordpress-importer`
    Then STDOUT should contain:
      """
      Success: Updated 1 of 1 plugins.
      Skipped updates for: wordpress-importer
      """

Result

I also tried with themes but could not reproduce the error.

wp theme install niya --version=1.0.0 --force
wp theme install obulma --version=1.0.5 --force
wp theme install simple-life --version=2.5.1 --force

Then:

wp theme update --all --exclude=niya

I think that I understand the problem. It feels like the plugin/theme in question is throwing a fatal error at the moment of the update. While inspecting the code, I was able to determine that the plugins/themes in the --exclude are properly removed before any attempt of the update.

What probably is causing this issue is that the plugin/theme is loading when the wp plugin update runs (and probably other commands), which as expected should show an error.

@kkmuffme have you tried to run that command appending at the end of that --skip-themes --skip-plugins? This might update your plugins (excluding the ones set in the --exclude) even though a plugin/theme is causing issues in WordPress.
