Aromatization turns "Implicit H count" values to Valence values (and vanish if Implicit H count=1)

**Describe the bug**
Aromatization turns "Implicit H count" values to Valence values (and vanish if Implicit H count=1)

**IMPORTANT:** "Implicit H count" values are not visible on the canvas because of https://github.com/epam/ketcher/issues/3529 issue

**Steps to Reproduce**
1. Load from file (unzip first): [Aromatization turns Implicit H count values to Valence values (and vanish if Implicit H count=1).zip](https://github.com/epam/Indigo/files/14435928/Aromatization.turns.Implicit.H.count.values.to.Valence.values.and.vanish.if.Implicit.H.count.1.zip)
2. Press Aromatize button (Ctrl+Alt+A)

**Actual behavior**
Aromatization turns "Implicit H count" values to Valence values (and vanish if Implicit H count=1)

**Expected behavior**
Aromatization works as intended

**Environment details (please complete the following information):**
- Indigo Toolkit Version 1.18.0-rc.9.0-gc7efb4e71-wasm32-wasm-clang-12.0.0
- Ketcher Version 2.18.0-rc9 Build at 2024-02-27; 16:16:47
- Chrome Version 122.0.6261.70 (Official Build) (64-bit)
- Win10
- Issue found while testing https://github.com/epam/Indigo/issues/1446

Reproduce the failure using the attached ZIP, then press Aromatize (Ctrl+Alt+A) and compare the implicit H count and valence values before and after. Trace the aromatization entry point and related handling of these values; done means implicit H counts are preserved as expected and the regression is covered by an appropriate test.
