Can not upload multiple files if "Upload to SD" (aka streaming) is disabled via uncheckiing "Enable SD supprt"

[solidus0079]

The problem

1. I wanted to disable the "Upload to SD" button (aka streaming gcode) since I click it by accident sometimes and it takes forever.
2. That button is removed by unchecking "Enable SD support" in Settings -> Features
3. With "Enable SD support" unchecked, you can no longer upload multiple .gcode files at once via the remaining "Upload" button. Multiple files at once was possible when the "Enable SD support" button was checked, but the functionality goes away when it is unchecked.

Did the issue persist even in safe mode?

Yes, it did persist

If you could not test in safe mode, please state why ("currently printing" is NOT an excuse!)

Occurs in safe mode.

That'll be something I missed in #4633, so I've fixed it with #4953

Since 1.10 is already in RC phase, it will probably be in 1.11.

Just merged your PR after fixing the issue with it. I've also marked this as bugfix release relevant, so it might also end up in a future 1.10.x bugfix release after stable is out.

Backported to 1.10.1.

1.10.1 has just been released.
