HOTFIX: Fixed issue with export file and instrument model using the NCBI Exporter

[joshsadam]

Description of changes

The NCBI export page was failing to actually export samples :(. This is lousy.

What was wrong:

• Files were not sent as a required field. This has been updated now.
• Sample field values were not properly being sent. The structure of the field was field: {value: VALUE}, and was attempting to send it as such. This was fixed by getting the actual value and sending it.

To test:

1. Select samples (that have files) from the project samples page.
2. From the menu above the table: Export > Upload to NCBI SRA
3. Fill in the fields for the submission details.
4. Select sample default values or fill in values for each sample.
5. To check the files, open up a sample collapsed region and select then deselect a file. A message should be displayed underneath them that shows the error message. Selecting another file should remove that error.
6. Once all fields are filled in, click submit.
7. If it redirects back to the project samples page then the submission was successful.
