Instead of calling GetUserMedia every time a user would like to make

LocalMediaStream works on the first call, but the call ending causes
the MediaStream (and it's tracks) to move to the ended state and that
switch seems to occur browser-side, outside of my control, and
subsequent calls have no media. Since clone is not available yet, I
figured the next best thing to do would be make a new MediaStream
with the existing tracks. I realize this may not work, but I'm not
sure what else I can do at this point.
Ah, I'm afraid that there's no real way to do what you want to do:
you're going to have to re-prompt the user for permission for each call.
I would expect your clone trick to work, once we get cloning working.
You may wish to follow this bug to keep abreast of progress:
https://bugzilla.mozilla.org/show_bug.cgi?id=910249
You can keep the MediaStream from gUM active (and that means the camera
light on, etc) by just not calling .stop() on it, and keeping a
reference to it. It doesn't have to be attached to a video element.
Likely you're calling .stop() at the end of the call, which means "I
never want to use this MediaStream again".
There are specs for constructing MediaStreams from tracks gotten from
other MediaStreams; we have not implemented those yet.
