fix: Cannot reconnect to server after unmounting FTP without closing …

…file manager

When using finished signal to trigger close(), the close event was being filtered
by QDialogPrivate::close()'s event filter. Changed to use buttonClicked signal
instead which is emitted before the filter is installed.

log: This fixes the issue where closeEvent was not being triggered properly when
closing the dialog.
