Ampersand in URLs being incorrectly escaped as an HTML entity

[timotheos-firestone]

Description:

When using Markdown-style links in Rocket Chat, the link generated escapes the ampersands as html entities incorrectly, meaning that clicking on the link will navigate the browser to a modified version of the link, not the actual link intended. The link preview seems correct, but the actual link is not.

Server Setup Information:

• Version of Rocket.Chat Server: 0.63.1
• Operating System: Ubuntu 16.04 LTS (4.4.0-119-generic)
• Deployment Method(snap/docker/tar/etc): SNAP
• Number of Running Instances: 1
• DB Replicaset Oplog: Enabled?
• Node Version: v8.9.4
• mongoDB Version: v3.2.7

Client Binary

• Rocket.Chat+ Version 2.10.5
• Windows 7 Professional x64 Service Pack 1

Steps to Reproduce:

1. Send the message [Test](https://appdb.winehq.org/objectManager.php?sClass=version&iId=34726)
2. Click on the link (not the preview link)
   

Expected behavior:

Browser should navigate to https://appdb.winehq.org/objectManager.php?sClass=version&iId=34726

Actual behavior:

Browser navigates to https://appdb.winehq.org/objectManager.php?sClass=version&iId=34726 (note & in link) which is actually an entirely different page.

Closing this, since - if I'm not mistaken - this is a duplicate of #6719.
