An error crept in, resulting in:
```
[task ...] InterpreterError: InterpreterError: infix: [..] expects integer [..] integer
```
At some point, `suite` became a string name and not an object with a
string `name` member. However, in the interim, the diversity of
`command` structures has made the template approach untenable.
Therefore, this commit converts `GeckoProfile` to a `TryConfig`. The
existing test clearly wasn't helpful, and it doesn't really map to a
`TryConfig` test, so it was removed.
