Fixed Error report handler initialized before required libraries loaded

Affected version
2.1.4

There's an edge case in the core startup system that sets the error report handlers at a point where the required libraries for them to actually be executed aren't loaded yet (specifically between lines 70 and 71 in src/XF.php. If an error happens anywhere after that point before initializing the autoloader, the following error masks the actual error, making debugging pretty nasty:

Code:
[B]Fatal error[/B]: Uncaught Error: Call to undefined function XF\utf8_substr() in /var/www/forum/src/XF/Error.php:137 Stack trace: #0 /var/www/forum/src/XF/App.php(2189): XF\Error->logException(Object(Error), true, '') #1 /var/www/forum/src/XF.php(170): XF\App->logException(Object(Error), true) #2 [internal function]: XF::handleException(Object(Error)) #3 {main} thrown in [B]/var/www/forum/src/XF/Error.php[/B] on line [B]137[/B]

Thank you for reporting this issue. It has now been resolved and we are aiming to include it in a future XF release (2.1.5).

Change log:
Move setting up XenForo's error handling to be part of startSystem rather than standardizeEnvironment to ensure that the necessary classes/functions are available before they may be called.
Any changes made as a result of this issue being resolved may not be rolled out here until later.
