Trailing comments in query causes "string index out of range"

[andrewspode]

I'm using graphiQL for testing my API where it is fairly common practice to comment out a query and write a new one.

{info}

Will run fine.

{info}
#

Will fail with "string index out of range" on line 268 of lexer.py (char=body[position])

I could be wrong - but shouldn't that be a >= rather than >?

Thank you for the bug report, @andrewspode . You are right, that should be a >=.
