fix: correct inverted media guard in sendMediav1.3.9

sendMedia returned when the assembled URL was non-empty — i.e. for every
deviation that actually has media — so the random-media endpoint served
an empty body and never sent the image. For a media-less deviation it
instead fell through to mediaURL[21:] on an empty string, panicking in
proxy mode. Guard on len == 0 so real media is sent and absent media is
a no-op.
