Slack plugin fails to send notifications for posts containing links

Using the most recent version of the Slack plugin, a post I created recently never got posted to Slack.

In there error logs, I see this message and backtrace:

Job exception: undefined method `absolute' for DiscourseSlack::Slack:Class

thank you @mcwumbly. Yes absolute method missing in latest commit. I think it was removed mistakenly. If yes then @tgxworld merge my PR below.

Fixed in

https://github.com/discourse/discourse-slack-official/commit/6eaf264df706d98cd7732880c28b233e6c047d36

with test cases added.

@vinothkannans Thanks for looking into this as well. I made some changes to the existing method instead of reusing the previous one. Thank you for your PR!
