When JWT value contains dot notation (e.g., user.name) to access nested
properties, the DefaultJwtConvertStrategy.addHeader() method adds HTTP headers
twice.
**Cause:**
```java
if (converter.getJwtVal().contains(".")) {
headers.add(headerVal, parse(...)); // adds correct value
}
headers.add(headerVal, body.get(jwtVal)); // always executes, adds null
```
**Result:**
Expected: username: `["john"]`
Actual: username: `["john", "null"]`
