add view_email to whitelist

[fishhelper]

Add the contact_view_email API to the white list so that the URL string "contact/view/email" is accepted.

Hello! You can fetch a single contact using their email address by doing:

ac.api("contact/view?email=test@test.com", {});

This is a cleaner approach because it doesn't repeat the word "email" (which this change would allow): ac.api("contact/view/email?email=test@test.com", {});

If we can help further with this, just let us know! 😃
