Sort on Agreement Status should sort by label

Overview:
Steps to Reproduce:

1. Create at least two agreements with different statuses
2. Do a search which displays agreements with a variety of statuses
3. Click "Status" column header in the results MCL
4. Note that the status does not sort alphabetically by displayed value in the results MCL

Expected Results:

Should sort alphabetically ASC by status label
Actual Results:

Sorts ASC by status id (I believe)

Additional Information:

Currently the sort applied is `sort=agreementStatus%3Basc`

I think the correct sort is `sort=agreementStatus.label%3Basc`

It appears that there is no neat way to map between column name and sort term in SASQ, rather that it directly grabs from the column name. We can intefere with the `onSort` function and insert `.label` where applicable, or take the slightly  easier route of renaming the column.

From "agreementStatus" to "agreementStatus.label" should do the trick.

NOTE: We don't want to change the internationalised column header, or any of the formatters, just the keys for AgreementStatus
