Allow issue body to be modified again while creating issue

[sn8to]

e.g. you make a typo in the original body, you can't go back and change the body without going to github and editing the issue because the ➕ was removed

Best I'm willing to do is replace message body rather than modify. That alright?

[sn8to]

Yeah I meant replace, e.g. ask them again for the new body.

Coolio that's fine.
