Replacement of peptide at the end of sequence on preset w/out base works wrong

[AlexeyGirin]

Steps to Reproduce

1. Go to Macromolecules mode - Sequence mode
2. Load from file: Replacement of peptide at the end on preset w_out phosphate works wrong.zip
3. Create custom preset without base and name it "No base"
4. Select last monomer (in view mode)
5. Click on "No base" preset in the library

Actual behavior "Confirm Your Actions" dialog appears Click YES System removes last peptide from the sequence

Expected behavior No dialog appears System replace A peptide with @ symbol

As per requirement:

4. If the user selects any number of monomers in view mode, and clicks on the monomer card in the library, all selected monomer on the canvas are replaced by chosen monomer from the library each
