commit f5661ec96ea4e30abea2ad0b218024c6c747071b
Author: Dennis Francis <dennis.fran...@collabora.co.uk>

tdf#93328 : Assign the ScInterpreter results back to ScFormulaCell...
when the formula cell type is unknown before interpreting, otherwise
the cell is treated as of type string later when used by the
interpreter.
Added unit-test testIterations() in ucalc that tests the
establishment of circular chain of references and editing of a
formula cell that already belong to the circular chain.
