Description

Currently, the contact images come from the local image server spun by status-go. This is great because it saves memory for images.

However, it makes it so that the image URL is always the same. Something like https://Localhost:46739/contactImages?publicKey=0x03c5ece7da362d31199fb02d632f85fdf853af57d89c3204b4d1e90c6ec13bb23c&imageName=thumbnail
So when the image gets updated in the DB, we get a signal from status-go that the contact got updated, but the URL is the same, so the comparison we do for the contact properties doesn't trigger an update (dataChanged).

The solution for that is to do similarly to this change done for communities, ie add a version query param:

• desktop: fix(community): fix community image not updating #16807
• status-go: feat(community)_: add version to image url to let clients update status-go#6118

Acceptance criteria

• addTimestampToURL is removed from the code
• Contact images update for ourselves and when others change it correctly, ie we don't need to restart the app to see the update.
