Samples not symlinked if project ID is empty in SampleSheet

[dfornika]

We often want to symlink all libraries for a specific project, but sometimes we just want to grab all the libraries on a run or just a list of arbitrary libraries regardless of the project. But we're currently excluding any libraries that have an empty project ID:

symlink-seqs/symlink-seqs

Line 271 in 99e4936

if 'sample_project' in sample and sample['sample_project'] != "":

symlink-seqs/symlink-seqs

Line 299 in 99e4936

if 'project_name' in sample and sample['project_name'] != "":

symlink-seqs/symlink-seqs

Line 327 in 99e4936

if 'project_id' in sample and sample['project_id'] != "":

We shouldn't exclude those libraries.
