[Bug] Saves not working with IndexedDB

[cjwin2000]

RomM version
3.03

Describe the bug
When using ingame save functionality (for example pokemon's ingame save on GBA), a save file is not created. Nothing shows in the browser console or network activity. Clicking on the emulatorJS save button creates a save that my browser downloads, but it is not automatically added to RomM, which is what I'm pretty sure the intended functionality is. Save states DO work properly.

To Reproduce
Steps to reproduce the behavior:

1. Launch a gb, gbc, or gba game that offers in-game save functionality (eg Pokemon leaf green) with built-in emulatorjs
2. Try to create a save with the ingame save function
3. Observe nothing happens. No save file is created on the server, there is no browser console activity, and there is no network activity. Comparatively, observe the following:
4. Now try clicking the "export save file" button and observe that the save file starts to download to the browser's download folder
5. Now try creating a save state and observe that it is automatically saved to the server

Expected behavior
When using the ingame save mechanic, a save file should be generated and saved to the RomM server.

Seeing the same issue; tested with Firefox and Chrome with the developer tools open and looking for Network activity. Saw the following:

1. Tried Quick Save in EmulatorJS: no network activity. This is expected because EmuJS does not seem to send quick saves to the server.
2. Tried Save State from the menu. This worked and I saw two network transfers to the server. Later I did see that the game save states were present in the game menu.
3. Saved the game from within the game (Chrono Trigger, saved from the map). No network activity was shown and no game saves were present from the game menu in Romm after the fact.

EDIT: this seems related to #786 so I'll look there instead.

We're revamping emulatorjs integration in #1497 so i'm rolling this into #786
