System merge sequences while replacing selected monomers from the library in edit mode

[AlexeyGirin]

Steps to Reproduce

1. Go to Macromolecules mode - Sequence mode

2. Load from file: System allow to change monomers on the canvase in view mode (that is not allowed).zip
   

3. Switch canvas to text-edit mode

4. Select some monomers
   

5. Go to Library - Peptides tab

6. Click on D peptide

Actual behavior
All selected monomers changed to D peptide and all sequences merged to one

Expected behavior
All selected monomers changed to D peptide and sequences remain in place
As per requirement:

3. If the user selects any number of monomers in text-editing mode, and clicks on the monomer card in the library, one chosen monomer form the library should replace all the selected monomer(s) on the canvas. (user selects 5 monomers -> user selects A in the library -> 5 monomers get replaced by 1 A)
