Missing warning message when deleting all hydrogen bonds between two chains

[Zhirnoff]

Description:
According to the requirements, if all hydrogen bonds between two chains are deleted, a warning message should appear. However, this message does not appear when all hydrogen bonds are removed, allowing the chains to separate without confirmation.

Steps to Reproduce

1. Open Ketcher and draw two connected chains with hydrogen bonds between them. ( or open from file ketcher.zip)
2. Select sense and antisense chains and right click
3. Delete all hydrogen bonds between the two chains.
4. Observe that no warning message appears, and the chains separate immediately.

Actual behavior
No warning appears, and the chains are separated without confirmation.

Expected behavior
A warning dialog should appear before the chains separate.
1.5. If all hydrogen bonds between two chains are deleted, the user should get a warning message with the title "Deletion of all Hydrogen Bonds", and the text: "Deleting all hydrogen bonds will cause the separation of two chains. Do you wish to proceed?", and options "Cancel" (default) and "Continue".
