Avoid unnecessary memory allocation in dom_tree_to_gnc_numeric()
Return a gnc_numeric instead of allocations that every caller has to free.

This makes it easier to fix the use after free in the unit test function
equals_node_val_vs_split_internal() where the expression in the return
statement wants to use the allocated gnc_numeric.
