[CLNP-8097]Fixed a bug where the input field disappeared when a new message arrived while composing a quote message (#1398)

Fixes [CLNP-8097](https://sendbird.atlassian.net/browse/CLNP-8097)

The issue occurs because actions.setCurrentChannel(), which is called
when a message is received or a typing start event is triggered, resets
quoteMessage to null, causing the input field to disappear.
