What's new in this PR?

Issues

1. iOS does not send asset name when sending images
2. web sends 2 messages the first one with meta data including name and mimeType, and a second with where to get the asset from

Causes (Optional)

in both cases if asset restriction is on then the message will not be handled correctly and in iOS case it will show prohibated asset, and in web case it will not be visable

Solutions

1. add fail safe to check mimeType when name is missing, did not cover all cases but the most common mimeType, this should be enugh tho
2. allow handling of assets with data and no name since it will be handled later in the code by getting the type of the first message
