tdf#128894: xlsx-import : Do not share tokens between cells...

which are part of a xlsx-shared-formula along a *row*.
If we do, any reference-updates on these cells while editing
will mess things up.

For example a shared formula "=A30+1" used for a few cells in
the first row (say, A1, B1, C1 and D1) and on deleting a row,
say row#5, the reference update operation will decrement the
row index of all tokens in A1, B1, C1 and D1. But if they
share tokens, they all end up pointing to row#26 instead of
row#29 as each cell is updated which amounts to decrementing
4 times instead of once.

However shared formulas along columns are not affected by this
bug, when tokens are shared since we use formula-groups which
only keeps one copy of token array for the entire group and
reference-update code is designed to correctly work with
formula-groups.
