Line 225 Column 17: The pattern {'error', 'unauthorized_role'} can never match the type {'error','not_found' | 'token_timeout'} | {'ok',binary()}
```
If an empty username or password are given during the initialization
of `emqx_dashboard_admin`, it'll return just the atom `ok`, which
breaks the expected `{ok, _}` in `emqx_dashboard_app:start/2`.
```
{'EXIT',
{{failed_to_start_app,emqx_dashboard,
{emqx_dashboard,
{bad_return,
{{emqx_dashboard_app,start,[normal,[]]},
{'EXIT',
{{badmatch,ok},
[{emqx_dashboard_app,start,2,
[{file,
"/home/thales/dev/emqx/emqx/apps/emqx_dashboard/src/emqx_dashboard_app.erl"},
{line,32}]},
{application_master,start_it_old,4,
[{file,"application_master.erl"},{line,293}]}]}}}}}}}}
