809: Email created from "Report a bug" hyperlink : free from + signs

[GimhaniU]

These strings were encoded using URL.encodeQueryString() which causes spaces to be replaced with + signs. This pull request removes this and directly add the string to mail object. fixes 809.

However, this fix causes newlines too removed.

Hi @GimhaniU !

I hope that you are fine and well!

Much time later, I've tested your Pull Request, and I found that it does fix the issue #809, but it creates another issue: there is no more any carriage return in the email template. In order to merge your piece of work, this side-effect should also be fixed. Do you think you can work on it ?

Best,

Olivier.
