Fix cancellable context detection in `AdaptCmd` 

`AdaptCmd` was previously checking for a `.WithCancel` suffix
on context strings, however it's possible for a context to be
cancellable without ending in that suffix, such as when
`context.WithValue` was called after `WithContext`, e.g.:

```go
context.Background.WithCancel.WithValue(type trace.traceContextKeyType,
val <not Stringer>).WithValue(type api.DryRunKey, val <not Stringer>)
```
