A missing module creates errors in the diagnostics

If one of your annotations refer to a non-existing Model it will create a fatal error inside recess/diagnostics/output/exception_report.php
It says that printType cannot be re-declared.
Wrapping it with:
if (!function_exists('printType')) { /function here/ }
propagates the error to the next function.
After wrapping all functions the exception_report.php file works and returns an error from printCodeSnippet() that says that the $file parameter is empty.
Fixing the misspelled Model fixes the problem.
