Global dotnet tool install not finding global tools after installation on Linux with SDK installed

I'm trying to install several .NET Core Tools globally and it looks like the installation is working fine, however the path to launch the files does not appear to be set properly.

What I'm doing:

* `dotnet tool install -g LiveReloadServer` (or whatever none of them work)
* Close the terminal
* Start terminal
* Run `LiveReloadServer`

This results in `command not found`


The tools are installed properly it looks like:


Just not linked properly via `PATH`.

### Additional Information
I installed the SDK from the Dotnet download page here, using the instructions on that page:

https://docs.microsoft.com/en-us/dotnet/core/install/linux-package-manager-ubuntu-1910#install-the-net-core-sdk

Install seems to work fine otherwise - I can build and run projects etc. But it looks like the installer didn't add the path to `~/.dotnet/tools` (or any `.dotnet` path).
