[SECURITY] Prevent information disclosure in tests bootstrap

Both, the UnitTestsBootstrap and FunctionalTestsBootstrap set
display_errors to 1 which shows errors and warnings by default. If you
call those scripts within web context the files can't be loaded and the
error message shows the website root path. The patch adds proper checks
before files are loaded and exits if an error occurs.
