Very slow startup if network shares are mounted

[Sergey "Shnatsel" Davidoff]

When I have an FTP server mounted via GVFS, Noise window freezes after startup for quite a while. When I enable debug output, it prints:

[_LOG_LEVEL_DEBUG 22:42:53.854788] CDRomDeviceManager.vala:62: Found device at ftp://<email address hidden>/ is not an Audio CD. Not using it
[_LOG_LEVEL_DEBUG 22:42:55.631451] iPodDeviceManager.vala:69: Found device at ftp://<email address hidden>/ is not an iPod. Not using it
[_LOG_LEVEL_DEBUG 22:42:56.546425] AudioPlayerDeviceManager.vala:62: Found device at ftp://<email address hidden>/ is not an Audio Player or Android Phone. Not using it

And this output repeats 4 times!

Something has to be done about it. Either make device discovery asynchroneous, or take some shortcuts to ignore network shares right away, or both.
