Fixes #554 : Missing notes
Fixes #554 : Missing notes

It is related to a problem arised with changes in #520 and partially corrected with commit 4b969a2248e649bb1e886ae2fc8f6794e55b2107.

The (big) problem affects only to Standard Rich text notes (non multi-level tree): they are being saved empty after the second time the file is saved, if its content have been not modified.
