Extra "end" is getting added for single line definitions

[jittrfunc]

Hi, using this extension I am getting an extra "end" added for single line definitions.

Example:
def test; "do something"; end (Here another "end" is getting added after pressing enter)

I have created a PR #3 to fix the same. You can review the changes and also pull it in if satisfactory.

#3 is merged, fixed release for the market place is on its way. Thanks again 👍
