Removed unspecific error message in kernel/error/view.php

At the moment, every error is logged to error.log with the unspecific message "Error ocurred using URI: […]", although a more specific error message is already logged right before, e.g. "Undefined module:"

Thus, the line
```php
eZDebug::writeError( "Error ocurred using URI: " . $_SERVER['REQUEST_URI'] , "error/view.php" );
```
should be removed from the file `kernel/error/view.php`, to avoid the flooding of the error.log file.
