mailto link: Email address is ARRAY(...)

The API returns inconsistently either an array or a string for author.email take the following examples:

http://localhost:5000/v1/author/NEILB is indexed as "email" : "[email protected]" (locally)
https://fastapi.metacpan.org/v1/author/NEILB is indexed as "email" : ["[email protected]"]
https://fastapi.metacpan.org/v1/author/REHSACK is  "email" : "[email protected]"

So update the template logic to check first if an array email.0

Also first check for asciiname before name, which should prevent breakage in the mailto 'URI' for cases like:
"asciiname" : "Audrey Tang"
"name" : "☻ 唐鳳 ☺"
I don't think any validation exits on the asciiname field to validate it is actually ascii, perhaps this needs to be added as a seperate ticket.

Closes metacpan#2237
