### Problem Description

When testing datemath with complex date strings, I found that some worked and some didn't. I narrowed it down to the existence of the `|` pipe character in the string.

@dakrone seems to think this may be due to how the `IndexNameExpressionResolver` works differently for security-enabled vs. non-security-enabled clusters.

### Steps to Reproduce

## Security Disabled Cluster
```
curl -XGET 'http://localhost:9200/%3Cdatemath-%7B2001-01-01-13%7C%7C%2B1h%2Fh%7Byyyy-MM-dd-HH%7C-07%3A00%7D%7D%3E'
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Cross-cluster calls are not supported in this context but remote indices were requested: [<datemath-{2001-01-01-13||+1h/h{yyyy-MM-dd-HH|-07:00}}>]"}],"type":"illegal_argument_exception","reason":"Cross-cluster calls are not supported in this context but remote indices were requested: [<datemath-{2001-01-01-13||+1h/h{yyyy-MM-dd-HH|-07:00}}>]"},"status":400}%
```

## Security Enabled Cluster

```
curl -XGET -u sample -p 'https://secure.cluster.io/%3Cdatemath-%7B2001-01-01-13%7C%7C%2B1h%2Fh%7Byyyy-MM-dd-HH%7C-07%3A00%7D%7D%3E'
Enter host password for user 'sample':
{"error":{"root_cause":[{"type":"index_not_found_exception","reason":"no such index [datemath-2001-01-01-14]","index_uuid":"_na_","index":"datemath-2001-01-01-14"}],"type":"index_not_found_exception","reason":"no such index [datemath-2001-01-01-14]","index_uuid":"_na_","index":"datemath-2001-01-01-14"},"status":404}%
```
