User message avatar slot is only displayed when avatar has a value

[NINI1988]

Describe the bug

48092be#diff-f3d6d7397d0e697abbf31431377ad9b953fe312e3cf9267331d2e2984ed9b529R37-R45

We want to overwrite the message avatar slot.
But the message avatar slot is only displayed when message.avatar has a value, so we set it for example to true,
and before it is possible to overwrite the message-avatar_ slot a request is already made to request the avatar for the background image true.

Our avatar is generated from multiple images, so it is not possible to just use one url in avatar.

Proposal

Split v-if="message.avatar && message.senderId !== currentUserId"
into v-if="message.senderId !== currentUserId"
and move the first part of v-if="message.avatar" to the inner div.

Device (please complete the following information)
