I suppose this should be considered a bug, but reset-prompt only
redraws the prompt if there was one before it was called.  I imagine
this is meant as an optimization so it doesn't have to re-fetch the
value of the variable if it was never set.  So all you need to do is
add

RPROMPT=''

to your .zshrc, probably right after the "zle -N self-insert" in your sample.
