Minor changes in source code and readme for tasks-rs QS required

There are instructions to remove the comments from some lines in readme for tasks-rs QS:

// import com.fasterxml.jackson.annotation.JsonIgnore;
// @JsonIgnore

These lines are present in the source code of the QS, but some of them cannot be searched (ctrl+c + ctrl+f) because there is different number of spaces after the // in readme and in the actual source code used in QS:

//import com.fasterxml.jackson.annotation.JsonIgnore;
//    @JsonIgnore

I suggest using this pattern without additional spaces in all the cases:

//import com.fasterxml.jackson.annotation.JsonIgnore;
//@JsonIgnore

The suggested pattern is the same as is used in other comments mentioned in the readme:

//@Produces({ "application/xml", "application/json" })
