Glitch in the creating PR from issue

[shresthagrawal]

if the user creates an issue for a new release the bot creates a pull request and adds the comment in the following way

Hi,
you have requested a release PR from me. Here it is!
This is the changelog I created:

Changes
Update README.md
You can change it by editing CHANGELOG.md in the root of this repository and >pushing to 2.2.1-release branch before merging this PR.
I didn't find any files where version is set.

The same comment is generated even if their is or isn't a CHANGELOG.md available in the repo. Which is confusing, either it should tell that their is no CHANGELOG.md (as it does for the version files) or it should create a CHANGELOG.md with the auto generated changelogs.
