delete icon not needed for primary email address

[Steven]

Environment tested: Master
Browser tested: Chrome

===================
Manual Test Script
===================

1) user browse to Main menu > Profile > Contact information
2) User adds multiple email addresses
3) User tries to delete primary email address

Actual Result: error message is displayed "You cannot remove your primary email address."

Expected Result: If user cannot delete a primary email address, then the delete icon next to the primary email should not be displayed.

[Kristina Hoeppner (kris-hoeppner)]

This is a bit more complicated: When a user changes the radio button to one of the other email addresses, they can delete the primary email address.

Scenarios:

1. Only one email address: There should not be a delete button as the only email address cannot be deleted.

2. One or more email addresses: The primary email does not have delete button. When the primary address is changed, it should receive the delete button and the now primary email address gets it removed.

Changes have been made to reflect some discussion:
a/ If the email is the primary email (will be radio button checked) do NOT have the delete icon.

b/ If a new email is added but not yet validated (user has not clicked the link sent in the validation email), it will display the email address with a disabled radio button, a validation message, and a delete icon.

c/ If another email address is added and has been validated (via clicking the link sent in the validation email) but NOT primary, it will display with a radio button that is enabled and a delete icon

NB: All changes, updates etc... must be "saved" via the "save profile" button on bottom of page to see any changes take place.

There seems to be the following problems

1) Delete button alignment with verified and non verified email addresses
2) The non-verified button is bigger / icon not in center of button
