Binlog server: handle filestem in blr_handle_missing_files()

Browse Source 
Routine blr_handle_missing_files() is called by
blr_handle_fake_rotate().

Field ‘filestem’ is updated in order to avoid wrong file name creation.

Additionally router is not creating any missing filenames if
router->binlog_name is empty (no previous binlog files)
