Subject: [PATCH] fix(filewatcher): handle removed directories #8800

When setting up manual recursive watching on folders (as is the case under Linux),
the watching thread should not exit if a directory no longer exists.
This is likely to occur within build output directories and it should
not be the cause for interrupting the daemon.
