Fix formats in the comments

[IzN432]

Summary:

Addresses part of #1299

Changes Made:

• Remove the extra full stop after Team Chose [ {{ tag }} ] and Originally [ {{ tag }} ] from commented templates
• Replace the newline after **Reason for disagreement:** with a space from commented templates

Proposed Commit Message:

Fix incorrect format of commented templates

Templates for the tester response phase's comments on GitHub found in 
the code comments are incorrect. The templates include an extra full 
stop after "Team Chose [ {{ tag }} ]" and "Originally [ {{ tag }} ]" and 
a new line after "**Reason for disagreement:**". 

This causes the issue to be filed under faulty issues when viewed in the 
Tester response phase on CATcher.

Let's fix the formats by removing the extra full stops and replacing the 
new line with a space.

Great PR that fixes the comment inaccuracy of the template. Just some github related comments.
In this case the linked issue contains multiple parts that cannot be fixed in this one PR. Therefore, in order for github to not automatically close the linked issue on merge, could you change the Fixes [issue_number] to something like Addresses part of [issue_number] in the PR description.
Additionally, it would be good to update the proposed commit message to something more descriptive for standardization regardless of PR size. You may refer to the git convention linked to by our CATcher documentation. I will put a direct link here.
