Fix ectest to not check a case which isn't guaranteed to work, and which we don't use.
When I removed the special case for EC_ILOG(0) in commit
06390d082dcdfa8addb3dde337543bc0f0ebae44, it broke ec_dec_uint() with _ft=1
(which should encode the value 0 using 0 bits).
This feature was tested by ectest.c, but not actually used by libcelt.
An assert has been added to ec_dec_uint() to ensure that we don't try to use
this feature by accident.
ec_enc_uint() was actually correct, but support for this feature has been
removed and the assert put in its place.
