InvalidTemplateResourceException for fluid emails send from EXT:install
When logging into standalone install tool, with activated email delivery, the following exception is thrown:
(1/1) #1257246929 TYPO3Fluid\Fluid\View\Exception\InvalidTemplateResourceException Tried resolving a template file for controller action "Standard->Security/InstallToolLoginAttempt" in format ".html", but none of the paths contained the expected template file (Standard/Security/InstallToolLoginAttempt.html). The following paths were checked: /home/daniels/Projects/own/website-typo3/project/private/typo3/sysext/core/Resources/Private/Templates/Email/, /home/daniels/Projects/own/website-typo3/project/private/typo3/sysext/backend/Resources/Private/Templates/Email/
The reason is that paths for EXT:install, which provides templates, are not added to $GLOBALS['TYPO3_CONF_VARS']['MAIL'].
