Fix an issue where overwriting a non-computed cell caused the Value of the formula cell is not computed error

[sequba]

Context

Analysis:
In some cases, a non-computed cell (formula cell or array cell) throws Value of the formula cell is not computed error when being overwritten by other value. It shouldn't happen. We don't need to compute a value that is about to be gone.

Fix:
Checking for non-computed cells before overwriting.
