This was probably a typo introduced in
7453e2979f.
Unfortunately, AWS SDK is so well made that this typo became an assert
error in production.
AWS Outcome constructors contains
```
// Move error from other type of outcome
template<typename RT, typename ET,
enable_if_t<!std::is_convertible<RT, R>::value &&
std::is_convertible<ET, E>::value, int> = 0>
```
which means that when:
* RT → R is not possible (e.g. PutObjectOutcome → HeadObjectOutcome)
* ET → E is possible (e.g. S3Error → S3Error)
Then, we will instantiate the error-moving outcome constructor which
asserts `!o.success`… Though, the original outcome indeed succeeded.
