Ability to filter or export or query confirmed (double opt in) emails

[collegewap]

Is your feature request related to a problem? Please describe.
Currently, the admin portal has no option to query/filter/export only confirmed emails.

Describe the solution you'd like
It could be great if there is any one of these features:

• Ability to query in the Advanced section
• Ability to filter out only confirmed emails
• A column in the export, which says confirmed or not.

Once you go inside a list (Lists -> Click on the subscriber count on the respective list), it's possible to query subscribers by status.

However, I just discovered a bug that breaks the export for this query. Fixed it in #aaf5080 which will be available in the upcoming release (today).
