Incorrect imports when using union fragment with `dedupeOperationSuffix: true` and `inlineFragmentTypes: 'combine'`

### Which packages are impacted by your issue?

@graphql-codegen/near-operation-file-preset

### Describe the bug

Using `dedupeOperationSuffix: true`, `inlineFragmentTypes: 'combine'`, and using union type together causes incorrect import names.

You'd expect that given the following fragment,

```graphql
fragment UINodeFragment on UINode {
... on TextUINode {
id
content
}
... on ImageUINode {
id
url
}
}
```

which generates

```ts
export type UiNodeFragment_ImageUiNode = { __typename?: 'ImageUINode', id: string, url?: string | null };

export type UiNodeFragment_TextUiNode = { __typename?: 'TextUINode', id: string, content?: string | null };

export type UiNodeFragment = UiNodeFragment_ImageUiNode | UiNodeFragment_TextUiNode;
```
importing and using `UINodeFragment` in another operation will generate code that imports `UiNodeFragment_ImageUiNode` or `UiNodeFragment_TextUiNode` or `UiNodeFragment`.

Instead, generated code imports `UiNodeFragment_ImageUiNode_` and `UiNodeFragment_TextUiNode_`, with additional undercores at the end.
