fix(wm): properly store tile state when caching ws

Previously, when caching a workspace config for a monitor it would
simply store the `DefaultLayout` on `layout` even if the original
workspace config had the `layout` as `None`, which makes komorebi create
a workspace with the `layout` as default `BSP` and the `tile` set to
`false`.

This resulted in floating workspaces would becoming tiling `BSP`
workspaces after a monitor disconnect and reconnect.

This commit fixes this by turning the `layout` to `None` when `tile` is
`false`.
