I'm getting an error when I'm executing my dsl scripts after upgrading config-file-provider to version 2.17.

Steps to reproduce this error:

1. Create a Freestyle project
2. Add a Build Step: Process Job DSLs
3. Use the provided DSL Script (dummy for this example):

   configFiles {
     customConfig {
       id('123456789')
       name('Old_Config_File')
       comment('This is a comment.')
       content('My Content')
       providerId('')
     }
   }
   

After save and build the job, I get this error:

Processing provided DSL script
ERROR: Found multiple extensions which provide method customConfig with arguments [script$_run_closure1$_closure2@830385b]: [[org.jenkinsci.plugins.configfiles.custom.CustomConfig, org.jenkinsci.plugins.configfiles.custom.CustomConfig]]
Finished: FAILURE

If I use config-file-provider:2.16.4, this job finish SUCCESS

Could it be a regression or do I have to make changes in my script?
