[JW Lua] eachentrysaved can automatically remove the TieBackwards flag

[Robert Patterson]

This is definitely Finale resetting the tie end bit (as it can do at any
time.) The interesting part is, what's triggering it is saving the empty
layer 2 frame in bar 2. The `eachentrysaved` function uses FCNoteEntryCell
<https://github.com/finale-lua/lua-source/blob/master/built-in-functions/rgplua_built_in_functions.lua>to
hold the frames. By default, a frame for all four layers is created. (This
allows a script to insert notes into empty frames, for example.)

You can limit the layers it loads with SetLoadLayerMode. Then the empty for
loop will not reset the tie end:

local region=finale.FCMusicRegion()
region:SetFullDocument()
for e in eachentrysaved(region, 1) do
end

Weirdly, even freezing the accidental doesn't preserve it from this Finale
bug. A helpful addition might be a new loadlayermode that loads only the
frames that are there, which could be different cell by cell.
