Incorrect AthenaError in Aws::Utils::Outcome<T, AthenaError> Template

[livioso]

Describe the bug

AthenaError exists twice: First one here and second time here.

Due to a namespace problem, the Outcome template uses the incorrect AthenaError (second one), same problem exists for all these methods as well.

This causes the following code not to compile:

auto outcome = client.ListNamedQueries(request);

// this should & used to work, now fails :(
outcome.GetError().GetExceptionName(); 

Expected behavior

auto outcome = client.ListNamedQueries(request);
outcome.GetError().GetExceptionName(); 

Should work and probably use this class.

Current behavior

Aws::Utils::Outcome<T, AthenaError> template uses the incorrect AthenaError causing a compile error.

Steps to Reproduce

auto outcome = client.ListNamedQueries(request);
outcome.GetError().GetExceptionName();
