Request
User should be able to select all emails from a list of searched emails.

Select all appears if you long press in the inbox or click on a label, but it is not available if you search for an email or a term that will return multiple emails.

This appears in desktop but not in mobile app. It is an inconsistent experience.

Use Case
1. In the mobile app, make a search query that will return multiple emails. (Ex: "Amazon")
2. Long press on the the icon to the left of the email to enter multi-select mode
3. Select all should appear as an option at the top of the search list.
4. Click on select all to select all emails.

Acceptance Criteria
This should also apply to every environment
