Mobile app help page is intercepting deep links to riot.im/app (and gives unnecssary instructions to set your custom server settings to: matrix.org)

[lampholder]

To reproduce:

• get a phone
• go to https://riot.im/app/

We want fix this so deep links aren't intercepted and we don't tell users to set their custom homeserver to matrix.org :)

The simplest fix might be to disable the mobile instructions intercept page for https://riot.im.
