Subject: [PATCH] pdfjs: Reset canvas_logs in tearDownPdfJS and call validate
 (#289)

Reset the canvas_logs array in tearDownPdfJS to prevent accumulating
logs across benchmark runs. Hook up validate() on class Benchmark
so tearDownPdfJS() is executed at the end of the benchmark run to verify
rendering output and allow GC of the canvas logs and global PDFJS state.

Fixes #289
