[JENKINS-51218] EMail-Ext does not send email, because or empty recipients

I send my mail via groovy script in a multibranch-pipeline (blue ocean)

```
script
{
def currResult = getResultAsString(currentBuild)
def prevResult = getResultAsString(currentBuild.getPreviousBuild())
if (currResult != "SUCCESS" || prevResult != "SUCCESS")
{
echo 'send mail'
emailext body: '''${SCRIPT, template="my-html.template"}''',
recipientProviders: [[$class: 'DevelopersRecipientProvider'],
[$class: 'CulpritsRecipientProvider'],
[$class: 'UpstreamComitterRecipientProvider'],
],
subject: '[Jenkins]: ${JOB_NAME} ${BUILD_DISPLAY_NAME} - ' + currResult,
mimeType: 'text/html'
}

}

def getResultAsString(build)
{
def result = build?.result
if (result == null) {
result = "SUCCESS"
}
return result;
}

```

When creating a new branch and adding a commit which will fail this build,

jenkins will not send a email, with following message:

```
An attempt to send an e-mail to empty list of recipients, ignored.

```

However, when adding another commit to the same branch, jenkins, will now surprisingly have a commiter email address and can send the email.

So always the first build of a new branch, email-ext will not retrieve a correct email from the commit.

Can you please fix it?
