Merge 2cb897238c into 3a4ba01e01

this leaves out the name property AddressObject instead of setting it to undefined.

typescript 4.4 has a new check exactOptionalPropertyTypes which prevents accidentally confounding a missing property with a property which does exist, but has a value of undefined.

for maximum type safety, i'd like to keep this enabled in my project - but if i do, tsc complains about emailjs being imprecise about its types.
