Do not startEnvironmentEmulation for current store

[luigifab]

Description

This PR do not run startEnvironmentEmulation when the targeted store is the current store.
I don't know if this is the best way, for now our emails seem to keep working.

When a customer place an order, the new order email is sent.
To do that, startEnvironmentEmulation is triggered.

Three screenshots from BlackFire, before:


After:

OpenMage 20.0.10 / PHP 7.4.6

Manual testing scenarios

• Front: place an order, check new order email sent
• Back: go to any order / invoice / shipment / credit memo, click on send email button, check emails sent

Contribution checklist

I wouldn't have changed the $exception variable name but other than that wow... this is a great PR.

@luigifab did you check the phpstan notes?

[luigifab]

Yes for all, if $appEmulation is not defined, $initialEnvironmentInfo is also not defined.
