--filter-providers makes an exception #10932

Describe the bug
When using the --filter-providers option, I got this error:
ProviderReferenceValidationError: Test #1 ("Test Skill reads the config file first") references provider "gemini" which does not exist. Available providers: openrouter:deepseek/deepseek-r1, openrouter:free

To Reproduce

I have a test with following providers (that are matching provider configuration):

  - description: Test Skill reads the config file first
     providers:
       - gemini
       - openrouter:*

When running: npx promptfoo eval --filter-providers openrouter:*
i got this execption:
ProviderReferenceValidationError: Test #1 ("Test Skill reads the config file first") references provider "gemini" which does not exist. Available providers: openrouter:deepseek/deepseek-r1, openrouter:free

Expected behavior
The test should run on openrouter:* providers only, as indicated by the documentation:

CLI --filter-providers: If you use --filter-providers to filter providers at the CLI level, validation only sees the filtered providers. Tests referencing providers excluded by --filter-providers will fail validation
