Ran into some maliciously crafted .xlsx files that contained invalid XML, which triggered an unhandled rejection because the stream no longer had an error handler at that point. Seems like I introduced this bug myself back in #541, so it's only fair that I fix it.
The test case is a little out there, but I couldn't find another way to test for an unhandled rejection. The
workbook.xlsx.readFile
promise already got rejected as it was supposed to.
