[NTG-context] +tlig fails sometimes in mkiv

On c.t.t. there was a discussion about the TeX-ligatures -- and ---
for endash and emdash. It seems that the luaotfload/context code
fails for some font/mode combination: For some fonts +tlig works
with both modes, some works only with mode=base, and there was also
a report of font which doesn't work at all (Frutiger LT 55 Roman).

E.g. on my PC +tlig works for Arial (c:/windows/fonts/Arial.ttf)
tested with a current context minimals only with mode=base.  

\font\test="Arial:mode=node;+tlig"

\font\testb="Arial:mode=base;+tlig"

\starttext

\test -- --- abc %fails

\testb -- --- abc %works

\stoptext \bye
