Unit Test Reviews

Fixed the cue identifier unit test.

Fixed the cue timing general unit tests.

Replay to Caitlin Potter:
White space around the timing arrow (-->) is not required for the parser. However since the parser is also validating the syntax I've added the appropriate error messages, just remember that the cue will still be processed normally.

If the first or second line of a cue does not contain the timings then the cue is bad and discarded. I've also added the appropriate errors. Note however the parser does not return a failure. In fact this is how notes are handled.

You are correct that the second and first cues are treated the same. I've fixed that. I was thinking of something else.

I did not rename tests, though I did change "Seperator" to "Separator" on account of spelling, but that should have no real impact. However there was a discrepancy between the .vtt file names and what was reference in the code. I've changed that so it would load the correct files.
