fix: conflicts with uikit (#384)

## Changes

- Use `disconnectWebsocket` instead of `disconnect` (applied changes
from [PR
#1219](sendbird/sendbird-uikit-react#1219))
- Prevent changes to the theme if it has already been added by other
logic.
- Added `localCacheEnabled` flag to control the use of local cache in
the Chat SDK.

ticket: [AC-4281]
