RSDK-8831 - Add log for failing module restart

[cheukt]

log looks like

manager.go:834: 2024-09-20T12:18:41.701-0400        DEBUG   modmanager      modmanager/manager.go:834       Removed resources after failed module restart        {"module":"test-module","resources":["rdk:component:generic/myhelper"]}

could perhaps make the list a little prettier, but this will do for now.

Since we weren't waiting for OnUnexpectedHandler to actually exit, there's a chance that the log assertion we were waiting for to pass but the remove orphaned resources method to not have run yet. Could repro the failure with a sleep right before the mgr.removeOrphanedResources call. So added an extra log and wait for that log instead

Ah good find; the listed resource names in that log do look a bit gross, but the information gets across. You could build up a []string to log of the Stringified version of orphanedResourceNames, but I do not feel strongly. Thanks for fixing!
