Identifiers for `spdx-license-identifier` rules do not align with match

### Description

The `rule_identifier` value for matches does not align with the rule `identifier` available in `license_rule_references` for matching using the `1-spdx-id` matcher. It correctly creates a matching rule, but the hash at the end of the identifiers are different (see "How to Reproduce").

This prevents any kind of automation to reliably retrieve rule information for these kind of matches.

### How To Reproduce

1. Create a file with an SPDX license identifier comment:
```
echo "/* SPDX-License-Identifier: MIT */" > Application.java
```
2. Run ScanCode with the `--license-references` option:
```
scancode --json-pp scancode_output.json --license --license-references --license-text Application.java
```
3. In the [scancode_output.json](https://github.com/nexB/scancode-toolkit/files/13863418/scancode_output.json) (file attached) there is now one match with a `rule_identifier` that doesn't exist. And also one `license_rule_reference` with an `identifier` that is never user.
```
$ cat scancode_output.json | jq .files[].license_detections[].matches[].rule_identifier
"spdx-license-identifier-mit-e0e2f62999b9522e22ba5602a715c2acd64e958b"
$ cat scancode_output.json | jq .license_rule_references[].identifier
"spdx-license-identifier-mit-2410ec7d8cecfb84d911cb1c29ba44ab907b8b8f"
```

Note how the unique identifier/hashes at the end of the identifiers are different. Both refer to `mit` and the `license_rule_references[].text` and `.files[].license_detections[].matches[].matched_text` so it's certain they are referring to the same thing.
