fix: prevent user starting wails app twice (#709)

Browse source 
Fixes https://github.com/getAlby/hub/issues/467

The simplest change to prevent Alby Hub running twice in Wails mode
which could potentially cause corruption of the LDK directory. This is
equivalent to how the http mode prevents it, but even better because the
port is allocated even before the service starts.
