Fix WPT test: content-security-policy/reporting/report-only-unsafe-eval.html

This test doesn't pass, because there is a problem with Chrome's
implementation (See https://crbug.com/980127) and because there are two
problems in the test itself.
 1) t_spv.done() is never called.
 2) A typing mistake in "tsv_unreached_func"
