avoid to initialize ComposeChatAdapter(). This is way too much and freezes the app The Text composable is of course just a placeholder to replace it with a well designed Message. However it's important that no heavy work is done in the composable to avoid the freeze Signed-off-by: Marcel Hibbe <[email protected]>

fix #5773
First of all:
The app is doing way too much work on the main thread and this needs to be investigated in general. The problem described here has certainly only caused the barrel to overflow.
The problem:
I realized that the app is freezing when pinning messages.
As i wont have more time today, could you please take over if possible @rapterjet2004 ?
I debugged and found out this is happening because of
ComposeChatAdapter().GetComposableForMessage(message)in PinnedMessage.kt
Initializing a class like ComposeChatAdapter in a Composable is not a good idea. It does way too much work incl injections.
The log even shows needless repeating calls to
/ocs/v2.php/core/autocomplete/getwhen this is initialized.
I replaced it with a plain Text composable for now which seems to fix the freeze (please test and confirm!).
Spoiler:
I already realized that the ComposeChatAdapter is a problem in the last days and i modify/delete it in #5635
So there is no need to come up with a perfect solution but it should be good enough until #5635 is merged (which will not be for v23.0).
So as we need to release 23.0RC1 (postponed to tomorrow i guess) we need a lightweight Composable that does no heavy work behind the scenes. Just the messages text and author name and and maybe avatar is fine i think.
Best will be: Do the heavy work elsewhere and pass the ready to use data into the Composable, also inside ChatActivity might be fine.
