scan#setVersion is invalid.

I found a problem, it could be a mistake..

reproduce steps in hbase shell:

1. create 't11', {NAME => 'f1', VERSIONS => 1}

2.put 't11','r1','f1:q1','f1'

3.flush 't11'

4.put 't11','r1','f1:q1','f2'

5.flush 't11'

6.scan 't11', {RAW => true, VERSIONS => 10, FILTER => "(QualifierFilter (>=, 'binary:f1'))"}

the result:
1. 1.3.1 version
hbase(main):011:0> scan 't11', {RAW => true, VERSIONS => 10, FILTER => "(QualifierFilter (>=, 'binary:q1'))"}
ROW COLUMN+CELL
r1 column=f1:q1, timestamp=1569400085570, value=f2
r1 column=f1:q1, timestamp=1569400068958, value=f1

2. in 2.1.1 version
hbase(main):023:0> scan 't11', {RAW => true, VERSIONS => 10, FILTER => "(QualifierFilter (>=, 'binary:q1'))"}
ROW COLUMN+CELL
r1 column=f1:q1, timestamp=1569400122280, value=f2
