chef run is not failed when a minitest has a syntax error

[fnoeding]

minitest-chef-handler version: 1.1.0

When a minitest contains a syntax error, the minitest handler is simply aborted. It will not fail the chef run as expected.

Steps to reproduce:

• create a minitest file that contains a error that's triggered upon require, e.g. undefined variable or a syntax error
• run chef
• see that chef reports an exception (see below)
• the chef run will complete successfully

Expected behaviour:

• the chef run will be failed with an error message

Chef output when this happens:

[...]

It seems like errors during require_test_suites are not caught leading to this behaviour.
