[orca] Remove any pre-calculated values for other cells in row during generation

[Joanmarie Diggs <joanied src gnome org>]

    Remove any pre-calculated values for other cells in row during generation
    
    When generating the full contents of a row, not all properties apply
    to all cells in the same row (e.g. the pre-calculated-for-performance)
    string. Remove these before generation so we don't get bogus results.
