fixes #1209 adds emptyText to email address field

It seems a string "undefined" came back from Cookies.get instead of undefined? I dont recall seeing this before. Added placeholder text in the input field and therefore removed the title.
I agree with if statement formatting as above... I prefer the readibility of if statements vs ternary myself, but dev discretion on this one. I think the string "undefined" should be a constant here, ie
EMPTY_COOKIE_STRING = "undefined"
