Local lambda logging during contract tests all on one line

There's no line break after every log statement when running the sam cli and contract tests. End up with a dense one line log like this:
```
AWS::SES::ConfigurationSet [{"Name":["-"]}] deleted successfully[DELETE] handler invokedEND RequestId: dd5fb042-f25c-1a50-dd12-d410fa7311f8
```

Need to see what we can do to separate these out into individual lines. Should be a quick change.
