[PATCH] Fix crash when no message is selected Export this patch

Pressing `Enter` on a view that has not yet loaded messages (e.g. at
startup) would return `nil` from `Selected()`. Accessing `msg.Uid` on a
`nil` reference crashes aerc.

This patch moves the `msg == nil` check before accessing `msg.Uid` thus
avoiding the crash.

To test this patch repeatedly press `Enter` on startup.
