Current behavior
I am trying to override the default setting for the bootstrap checkbox type in the module declaration. This results in an formly/angular error: 'Error: No component factory found for undefined'. Not sure if I don't do it the correct way or that it is a bug.

Expected behavior
The default options can be overriden from the module.

Minimal reproduction of the problem with instructions

     FormlyModule.forRoot( {
      types: [
        {
          name: 'checkbox',
          defaultOptions: {
            templateOptions: {
              indeterminate: false
            }
          }
        }
      ]
    }),

See https://stackblitz.com/edit/ngx-formly-bootstrap-scp5pb

What is the motivation / use case for changing the behavior?
The bootstrap checkbox is defaulted to 'indeterminate', as seen here. I want to configure it default as not indeterminate.
