Don't not add a period to output basenames

[tlangs]

Description

A change was introduced last year to CheckFingerprint which made it only add a period to the end of the OUTPUT argument if it did not already end with a period. This causes errors in our pipeline when sample aliases end in a period, because we derive our cromwell outputs based on the sample alias concatenated with "fingerprinting_summary_metrics" and "fingerprinting_detail_metrics". If sample_alias is MyCoolSampleG.T., the output files should be MyCoolSampleG.T..fingerprinting_summary_metrics and MyCoolSampleG.T..fingerprinting_detail_metrics

@tlangs It's pretty confusing to have a sample name that ends in a period. Can we prevent that?

[tlangs]

The tool should respect what it's given, no matter if it looks ugly. Changing the output name is not documented and results in a lot of confusion when the tool spits out files with different names from what was specified and expected. I don't think its up to us dictate how people name their files.

[lbergelson]

I agree we should fix the tool, but it would also be nice if we did dictate what people put in their sample names so they didn't have dumb things like a period as the last character.
