Fix conversion from Snake Case to Camel Case

[guillaumealgis]

Fix a case where hello_world would be converted to helloWorldd when applying a Camel Case conversion.

(it's not actually strictly speaking related to these two naming conventions, but to the fact that the conversion removed characters (_) in the process, and the remaining space created at the end of the converted string is not "cleaned")

Hi, thank's for the PR, i tried but deleting a range seems to work for a single selection, when having multiple selections it fails.

This is the code used as example

{
  "a_cool_snake_key": "Snake!",
  "some_other_key": 42,
  "and_another_one": "What a great example"
}

I've submitted an update 3.2.1, that fixes this problem, please try it and if you notice anything we can work on this PR to improve the code.

Just tested 3.2.1 quickly and this works fine for me :)

I'm glad it's working.
