onclue is never called if the vtt file does not end with 2 blank lines

[evs-jjam]

vtt.js/lib/vtt.js

Line 1286 in 42ca104

self.oncue && self.oncue(self.cue);

self.oncue is never called if the last line is a single blank line instead of two.

A workaround I found is to add a couple of extra blank lines systematically as this does not seem to cause any undesired side effects but that feels very hacky.
