bitbucket-copy-commit-reference: BitbucketServer: call async convertP…

…lainSubjectToHtml with await

Method convertPlainSubjectToHtml in class BitbucketServer incorrectly
calls the async method convertPlainSubjectToHtml of the super class
GitHosting.  This causes errors later in the method `#insertJiraLinks`.

Add missing `await` to the callsite to fix this issue.
