Description of Problem:

Let's say I have a contact already for John Doe with email address
john.doe@domain.com.  Then John Doe emails me with his new address.  But,
he does not set the name in the email field, so all I have is the
john.doe@newdomain.com.  I right click on this email address and say "Add
To Contacts."  A dialog pops up and I enter in John Doe into the "Full
Name" field and click OK.

At this point, Evolution *should* say "Would you like to add this address
to your already existing contant?".  Instead, it happily creates a new
contact.  Now I have two contact for the same person -- with two different
email addresses.

Steps to reproduce the problem:
1. create a contact named John Doe with email address john.doe@domain.com
2. get an email from john.doe@newdomain.com (*without* a name set)
            - From should be "From: john.doe@newdomain.com"
            - *not* "From: John Doe <john.doe@newdomain.com>"
3. right click on address and say "Add to Contacts"
4. type in John Doe into the new dialogs "Full Name" field
5. click on OK.

Actual Results:

creates a brand new contact name John Doe with the new email

Expected Results:

should ask to merge new email into old contact

How often does this happen?
