longFormat() works for for QFeatures with and without rowvars:

> head(longFormat(qf))
DataFrame with 6 rows and 5 columns
        assay       primary     rowname       colname     value
  <character>   <character> <character>   <character> <numeric>

> head(longFormat(x))
  rowname      colname    value
1       1 control_atcc       NA
2       2 control_atcc 20.24148
3       3 control_atcc 18.88513
4       4 control_atcc 18.16084
5       5 control_atcc 19.18385
6       6 control_atcc 15.67467
> head(longFormat(x, rowvars = "nNA"))
