[processing] added missing method to custom field calculator dialog

A much better way of doing this would be to have the dialog extend qgsprocessingalgorithmdialogbase, or to take an approach like the one used in the raster calculator, with wrapper widgets. This is just a patch, since that option might require a larger amount of work.
