Compose Message "To" field allows adding sequence of characters as contact
Compose Message "To" field allows adding sequence of characters as contact

When we select this option, this sequence of characters (which is neither a
valid email address nor a phone number), gets stored in contact with type MOBILE.

Fix: In function canAddToContacts, adding a check to validate whether the contact
to be added is a valid email address or phone number. If not, user will not be shown
with the option "Add to Contacts".
