Admin bar menu dropdown has "MailPoet" first in Memberships menu

[kimcoleman]

Describe the bug
On the top bar / admin bar for WordPress admins, "MailPoet" is showing as the first menu item in the dropdown for 'Membership'. We should not add the menu item to this area and / or if we do, it should be last in list (after main PMPro menu items).

Isolating the problem (mark completed items with an [x]):

• I have deactivated other plugins and confirmed this bug occurs when only Paid Memberships Pro plugin is active.
• This bug happens with a default WordPress theme active, or Memberlite.
• I can reproduce this bug consistently using the steps above.

I agree we should remove this from the top bar menu.
