Error message is wrong for missing probability number (PEPTIDE1{(A:,C:20)}$$$$V2.0)

[AlexeyGirin]

Steps to Reproduce

1. Toggle to Macromolecules mode
2. Load using Paste from clipboard way: PEPTIDE1{(A:,C:20)}$$$$V2.0

Actual behavior Error message is wrong: Convert error! Given string could not be loaded as (query or plain) molecule or reaction, see the error messages: 'SEQUENCE loader: Invalid number.'

Expected behavior Error message should report that probability number is missing (in any case - invalid number for missing number is a wrong diagnostic)
