Print the this binding of a method without a space before the semicolon

The space was left over from when the printer spelled out `let self =`
by hand; no other statement puts a space before its semicolon.

JS modified (@this function):
Example:
    let even = @this (o, x) => x + o
Before (js):
    let o = this ;
After (js):
    let o = this;
