[orca-list] Image without empty alt should be ignored by Orca

[Alex ARNAUD <alexarnaud hypra fr>]

Dear all,

An user accessibility expert (in CC) tells me that image with an empty alt should be ignored by Orca.

As I understand this behavior is in the ARIA specifications.

I've tested on Debian Sid with Firefox 52 and 54 with the latest Orca from master.

I've written a simple HTML page to help you to test : https://framabin.org/?bf949f49fae8da72#5m653ypAYth5mt7A1zC9h+1MAyqFUlH1DgWRnbR2S7E=

Steps to reproduce :

1) Open the page in Firefox

2) Read the page with Orca

Result : Orca announced "image" when It encounters the image with the empty alt

Expected result : Orca should skip this image

Best regards.
