Description: When BROWSER is set, webbrowser.get fails because register_standard_browsers throws an error.

Work around: You can still use `webbroswer._browsers[key][1].open(url)` to open a browser. 


Operating system: macOS High Sierra v10.13.6


Reproduction 1:

```
➜ BROWSER=lynx python3

[Clang 9.1.0 (clang-902.0.39.2)] on darwin

>>> import webbrowser
>>> webbrowser.get()
