The Systemcheck in the browser (/index.php?module=Installation&action=systemCheckPage) runs just fine and reports no errors.

This error did not happen with Matomo 3 or 4.5. It startet after the Update from 4.5.0 to 4.6.1

Steps to Reproduce (for Bugs)

1. open a terminal
2. go into matomo directory
3. run php console diagnostics:run

Alterantively open the admin homepage (/index.php?module=CoreAdminHome&action=home&idSite=1&period=range&date=previous30). Here the "System Check" widget shows the same error as described above (Call to undefined function Piwik\piwik_fix_lbrace());
