Remove test for committing new Site/TGI/PopulationGroups

We don't generally want to add to the source of our synch, and this

is removed... but it's probably not useful.)
Whitespace.
Use Synchronize::Classes version of sample.
Remove disused/duplicate LIMS subject hierarchy classes.
Allow for create to return undef

This happens when SoftwareResult::create fails to create the result
because another process has already created it.  Then
SoftwareResult::get_or_create will look for and find the already created
result.
