feat(issueMatch): Fix issueMatch creation by adding createdBy field to handler

[BlakePatterson]

Task Description

While testing the os scanner, I found that issue match creation was failing after the addition of metadata to issueMatch. The new foreign key constraint on the created_by field was failing on issue match creation since the logic in the OnComponentVersionAttachmentToIssue event was not setting the created_by field.

To fix this I'll just add the Metadata.CreatedBy field to the new issue match using the same userId being used for the UserId field.

Acceptance Criteria:

• Add Metadata.CreatedBy field to the new issue match being created in the OnComponentVersionAttachmentToIssue event
• Issue matches should be created when component versions are attached to issues

Expected Test:

Testing by running the os scanner to see if issue matches get created correctly.
