[🐛 Bug]: Junit reports n * n test suites in case of grouping test specs to run sequentially

### Have you read the Contributing Guidelines on issues?

- [X] I have read the [Contributing Guidelines on issues](https://github.com/webdriverio/webdriverio/blob/main/CONTRIBUTING.md#reporting-new-issues).

### WebdriverIO Version

7.20.3

### Node.js Version

v15.14.0

### Mode

WDIO Testrunner

### Which capabilities are you using?

```typescript
{
    maxInstances: 1,
    browserName: 'chrome',
    acceptInsecureCerts: true    
}
```


### What happened?

In case if we use nested array inside `specs`:
```
specs: 
[
    [
        './test/specs/**/*.js'
    ]
]
```
and generating `junit` report:
```
reporters: ['spec', ['junit', { outputDir: `report` }]],
```
Report contains `n * n` test results with the same suite name and test case name. `where n - number of tests.`


### What is your expected behavior?

Expectiпg to have the same number of tests as we run.

### How to reproduce the bug.

To reproduce the bug I created demo repo:
https://github.com/igor-lantushenko/wdio-example
you can just run:
```
npm run wdio
```
this happens only in case of nested array (single worker) mode

### Relevant log output
Example of log file:
