two different people have identical names - identical idenicon is generated

[kofaysi]

Thank you for the great work.

Please, consider, generating identicon from an extended string. Currently it is generated based on the name of the contact. It would be more unique to generate identicons from a concatenated string of name telephone number and email and website, if any is available. Or just process the UIDs of the contacts, if available -- I see those in exported VCF

Steps to reproduce:
create two contacts with the same name
add different phone numbers and/or email addresses
generate identicons

Current behavior:
Identical identicons are generated for both of the contacts

Expected behavior:
Different identicons are generated for both of the contacts (differing in phone or email)
