Pull before export doesn't work for forms from Central

[kkrawczyk123]

Software versions

Briefcase v1.17.4.x, Java v1.x.x, operating system, Aggregate v1.x.x, Collect v1.x.x...

Problem description

Pull before export probably has never worked for forms pulled from Central. It works well for Aggregate but as Aggregate is getting more and more deprecated and finally will be replaced with Central, ao all functions should be available for Central.
On individual form export configuration pull before export checkbox is disabled for all forms pulled from Central.

Steps to reproduce the problem

1. Run Briefcase
2. Select the Remember password checkbox
3. Select export dir and pull before export checkbox on default configuration window
4. On pull tab log to Central server
5. Pull form
6. Send another submission from Collect to Central
7. Go to export tab
8. Export previously pulled form
   Only submissions pulled manually are visible in created csv file, newly sent submission is not pulled and not visible in exported file.

Expected behavior

• Newly sent submission should be pulled and visible in exported csv after using pull before export option
• On individual form export configuration pull before export checkbox should be enabled and choosable
