fix(workspace): fix race condition when loading

[max-nextcloud]

render is called first.
It awaits the import of FilesHeaderRichWorkspaceView.
updated is called in the meantime.
It failed during the if block as FilesHeaderRichWorkspaceInstance is not available yet.
render continues with the folder it started with, which had no workspace.

Not sure this is a good solution. But it does the trick for me.
