exception emails not getting sent

[KeeneState]

Briefly describe the issue.

When an internal server error occurs, emails that were getting triggered in PW 2.6 are no longer generated.

What did you expect to happen?

Receive email on error, sent to $config->adminEmail

What did actually happen?

No email is generated

Optional: Have you a suggestion for a possible fix?

WireShutdown.php sends the email if function_exists("wireMail"). I think that needs to be changed to function_exists("\ProcessWire\wireMail").

What are the steps to reproduce the issue?

1. Make sure $config->adminEmail is set, and server/dev environment supports wireMail
2. Break some code to generate a WireException. Hit broken code with browser. You should see the message "Unable to complete this request due to an error. - Error has been logged. Administrator has been notified."
3. Veiw inbox, outgoing maillog.

Tell us about the setup you experienced the bug in.

Linux, PW 3.0.34, PHP 5.6.x
$config->templateCompile = false;
$config->moduleCompile = false;
