[QGIS-Developer] QGIS processing model: extract specific attribute of a single feature to a string

[Ujaval Gandhi]

I can think of a slightly hacky way. Use the 'Basic Statistics for Field'
algorithm, and since your field will have a single value, use either the
Minimum or Maximum value output from it (works for string fields too) as
the parameter for another algorithm.
