FS#10913: fix file browser not updated on microsd insertion/removal. This is a synchro bug in dircache: the system send a SYS_FS_CHANGED message which is first handled by the main thread which rescan the directory but as dircache main treats the message after, the file browser get the old version... Workaround is to check message queue before opening a directory.
