[WIP Do Not Merge] N/A cannot be built into URL for filtering Datatables

[johnnyporkchops]

Summary (required)

• Don't link contribution amount when Employer is N/A since a value with a slash ("/") cannot be passes to the URL because it is a reserved char for a URL

• Whether we put N/A in a link to filtered datatable or a user puts N/A in the employer field on a datatable, the API call will always turn it into N%2FA. So while the filter tags and the checkbox select shows N/A verbatim, it is always calling N%2FA.(Which does not return only contributors who submitted N/A, verbatim) See screenshots in issue comment

• One mitigating factor to any concerns about not linking the amount on the profile page table is the existence of the "Filter this data" button directly above the table, allowing users to click through to the datatable.

• Resolves N/A for schedule A datatable not filtering correctly from canonical page #5220
