Add a simple unit test to SingleFastqInputFormat

[kkaneda]

Hi,

I was randomly reading the code and decided to add a simple test. I didn't go further since I wasn't sure this is something actually useful.

Could you please take a look? Thanks!

Even though SingleFastqInputFormat is written in java, the rest of our unit test code is in scala. Would it be possible to port this to scala using ScalaTest? We use the FunSuite style, which reads very similar to JUnit.

The source file will also need a license header, which is located in the repo at https://github.com/bigdatagenomics/adam/blob/master/LICENSE_header.txt.

Thanks for taking a look, @heuermh ! Ah, didn't notice that.

So, we have SingleFastqInputFormatSuite, and it seems that has sufficient coverage. I'll decline the PR.
