[EEG Browser] Events and Electrode Panels Not Showing

[jesscall]

Describe the bug
A previously merged PR (#7387) added features for Event and Electrode panels to populate with information from EEG BIDS files. Currently these features are not viewable because the links to events and electrode files are always null.

I believe this to be a result of this change in the code (see diff)

Loris/modules/electrophysiology_browser/php/sessions.class.inc

Lines 477 to 483 in 6356a1e

	$downloadLinks = [];
	if ($nSplit === 0) {
	$downloadLinks[] = [
	'groupName' => '',
	'links' => $this->getPhysioFileDownloadlinks($physioFile),
	];

Retrieval of the links data is not checking the proper array, there should be another level of abstraction:

Loris/modules/electrophysiology_browser/jsx/electrophysiologySessionView.js

Lines 207 to 219 in 6356a1e

	epochsURL:
	dbEntry
	&& dbEntry.file.downloads[3]?.file
	&& loris.BaseURL
	+ '/electrophysiology_browser/file_reader/?file='
	+ dbEntry.file.downloads[3].file,
	electrodesURL:
	dbEntry
	&& dbEntry.file.downloads[1]?.file
	&& loris.BaseURL
	+ '/electrophysiology_browser/file_reader/?file='
	+ dbEntry.file.downloads[1].file,
	}));

To Reproduce
Steps to reproduce the behavior (attach screenshots if applicable):

1. Go to EEG Browser
2. Click on '....'
3. Notice that you do not see Events or Electrode Panels (should look like screenshot in [EEG Browser] Signal Visualization, Events, Electrode map and EEG split files support #7387)

What did you expect to happen?
To see the panels.
