`UnnecessaryQualifier` emits false positive warning when using Guice `@AssistedInject`

The code below triggers an incorrect warning on `@InjectCurrentTimestamp`.

```java

class Test {

interface Factory {
Test create(String paramFromFactory);
Test create(Integer paramFromFactory);
}

@AssistedInject
Test(@Assisted String paramFromFactory, @InjectCurrentTimestamp now) {
}

@AssistedInject
Test(@Assisted Integer paramFromFactory, @InjectCurrentTimestamp now) {
}

}

```
