Missing "Loading" label in fatal error screen in Install Tool
Steps to reproduce the problem:
Upgrade TYPO3 6.2 to 7.6 with an enabled incompatible version, e.g. multicolumn 2.1.16, solr 3.0.0, tipafriend_plus 0.3.0
A fatal error is thrown and shows up the "Check for broken extensions" dialog. In the background the check for broken extensions is started, but the "loading" label isn't shown.
