Java: binary-search: update version file (v1.1.0 -> v1.2.0) and update error handling

[FridaTveit]

Please update the version specified in the binary-search version file from 1.1.0 to 1.2.0.

Please also make sure that the expected error handling in the robot-simulator tests is up to date with the canonical data for binary-search. Currently we expect a solution to binary-search to return -1 if the value searched for is not present. However the canonical data now indicates that this should cause an error in a way that is idiomatic to the language. I suggest throwing an exception in that case. Thoughts @exercism/java? 🙂

After any changes have been made to the tests make sure that the reference solution still passes the tests. If it doesn't then please update the reference solution so that it passes all the tests.

Background info: each exercise which has canonical data should have a version file. This file states which version of the canonical data the exercise implements. The version can be found at the top of the canonical data file for that exercise.

Had implemented this earlier with a new Exception. Made a PR regarding the same.

Oh no, I didn't see @anurag-rai already created a PR :) Closed mine.

@chungngoops Hey, I'm so sorry I didn't see your comment before making my PR. We had the same idea to use Exception though :)

@anurag-rai, no problem bro! Happy to work on other issues!
