grand(1,"prm",m) yields an unsqueezed size([size(m) 1]) hypermatrix (Regression)

Reported by Samuel GOUGEON (@sgougeon)

BUG DESCRIPTION:
----------------
Scilab 5.5.2 was OK. Scilab 6.0 shows the following bug:

--> m = rand(2,3)
 m  = 
   0.6488563   0.050042    0.4104059
   0.9923191   0.7485507   0.6084526

--> m = grand(1,"prm",m)
 m  = 
(:,:,1)   <<<<<<<<<<<
   0.7485507   0.9923191   0.4104059
   0.050042    0.6084526   0.6488563


--> size(m)  // !
 ans  =
   2.   3.   1.

--> ndims(m)
 ans  =
   3.


ERROR LOG:
----------
none. Unsqueezed result. The final singleton dimension should be automatically squeezed.


HOW TO REPRODUCE THE BUG:
-------------------------
m = rand(2,3);
m = grand(1,"prm",m);
ndims(m)==2
and(size(m)==[2 3])
