Mattermost-server: Inline SVG images in Markdown are not displayed

[mattermod]

Originally reported on GitHub: https://github.com/mattermost/mattermost-mobile/issues/1481

SVG’s have a special setting, EnableSVGs, in the server configuration that tells the client if the SVG should be rendered or not.

react-native-svg added support to load SVG's from a uri and the dependency needs to be updated as well in the project.

Difficulty: Medium

Repro steps:
1) Post the following:

<![Mattermost](https://about.mattermost.com/wp-content/uploads/2017/08/Mattermost-Logo-Blue.svg)>(https://github.com/mattermost/mattermost-server)

Observed: The post is blank
Expected: The post shows the Mattermost logo as on the web app
