Resolves: tdf#148863 In JumpMatrix context use its dimensions for results

Problem was, that in array mode the result matrix of random values
was created according to the dimensions of the formula cell range
selected/resulting, which if transposed and displayed obeys the general rules of
a repeating vector if not a 2D matrix.

For example, entering the array formula
=TRANSPOSE(IF({1,1,1};RAND()))
(with , comma array column separator) is supposed to create a row
vector of 3 columns transposed to a column vector of 3 rows. The
selection created for the automatically determined result is 3
rows in one column, for which the RAND() was calculated, resulting
in a column vector

{
1
2
3
}

which transposed gave a row vector { 1, 2, 3 } and displayed for
one column such row vector is repeated as

{
{ 1, 2, 3 }
{ 1, 2, 3 }
{ 1, 2, 3 }
}

of which the first column displayed is the repeating first value 1.

With this change the dimensions of the JumpMatrix created by
IF({1,1,1};...) is used to generate the RAND() matrix, resulting
in a { 1, 2, 3 } row vector that then is transposed and displayed
as expected.
