NCBI Export fails to write library_name in submission XML

[apetkau]

Describe the bug

When exporting samples using the NCBI Export, there is a field in the form to enter the library name of a sample:

However, when looking at the produced submission.xml file, the <library_name> attribute is blank:

<Attribute name="instrument_model">Illumina HiSeq 4000</Attribute>
<Attribute name="library_name"></Attribute>
<Attribute name="library_strategy">WGS</Attribute>
<Attribute name="library_source">GENOMIC</Attribute>
<Attribute name="library_selection">RANDOM</Attribute>
<Attribute name="library_layout">PAIRED</Attribute>
<Attribute name="library_construction_protocol">CONSTRER</Attribute>

Steps to reproduce the problem

What were you doing when you encountered the problem?

1. Create an NCBI Export submission
2. Enter in information. I just left the default value for Library Name
3. Submit and example the submission.xml file produced. The library_name will be blank.

Expected behaviour

I expected the <library_name> to match what was shown in the web form.
